1. 1. Solve the equation |x + 2| = 62. Solve the equation |3x - 2| = 2x + 43. Solve |2x - 1| = |x + 4|tolong, Kak. ini harus sekarang
Jawaban:
1. |x+2|=6
x+2=6
x= 6-2
x= 4
x+2=-6
x= -6-2
x= -8
maka hp nya adalah x= -8; x= 4
2. |3x-2|= 2x+4
3x-2= 2x+4
3x-2x= 4+2
x= 6
3x-2= -2x-4
3x+2x= -4+2
5x= -2
x= -2/5
maka hp nya adalah x= -2/5; x=6
3. |2x-1|= |x+4|
2x-1= x+4
2x-x= 4+1
x=5
2x-1= -x-4
2x+x= -4+1
3x= -3
x= -3/3
x= -1
maka hp nya adalah x= -1; x=5
2. 2(x-1)+3(x+1)=4(x+4) Solve the Equation
Jawaban:
2x-2+3x+3=4x+16 ( dikali masuk ke dalam kurung)

x=15
3. 1. Solve for x when 16x = 2x + 56. 2. Solve for x when 14 = [tex] \frac{6 + 4x}{5x} [/tex] 3. Solve for x when 45 = 24 + 3x. 4. Solve for x if 5x2 + 20 = 1,000. 5. If q = 560 − 3p solve for p when q = 314.
1.
16x = 2x + 56
16x - 2x = 56
14x = 56
x = 56/14
x = 4
2.
[tex]14 = \frac{6 + 4x}{5x} \\ 14 \times 5x = 6 + 4x \\ 70x = 6 + 4x \\ 70x - 4x = 6 \\ 66x = 6 \\ \frac{6}{66} = x \\ \frac{1}{11} = x[/tex]
3.
45 = 24 + 3x
45 - 24 = 3x
21 = 3x
21/3 = x
7 = x
4.
5x² + 20 = 1000
5x² = 1000 - 20
5x² = 980
x² = 980/5
x² = 196
x = √196
x = 14
5.
q = 560-3p
314 = 560 - 3p
3p = 560 - 314
3p = 246
p = 246/3
p = 82

2x²-4x=2x²+4x
-8x=0
x=0
b. 3x/5 - 4x/20=2 (x 20)
4(3x) - 4x = 40
12x-4x=40
8x=40
x=40/8
x=5
A. 2x(x-2)=2x(x+2)
2x^2-4x=2x^2+4x
2x^2-2x^2-4x-4x=0
-8x=0
x=0/-8
x=0
B. 3×/5 -4x/20=2
(3/5)×(-4x/20)=2

13. solve the following equations.1-4 (2x+3)=5 (x-2)-3 (x-1)
Jawab:
x = [tex]- \frac{2}{5}[/tex]
Penjelasan dengan langkah-langkah:
1 - 4(2x + 3) = 5(x - 2) - 3(x - 1)
1 - 8x - 12 = 5x - 10 - 3x + 3
-8x - 11 = 5x - 3x - 10 + 3
-8x - 11 = 2x - 7
2x + 8x = -11 + 7
10x = -4
x = [tex]\frac{-4}{10}[/tex]
x = [tex]- \frac{2}{5}[/tex]
[tex]1 - 8x - 12 = 5x - 10 - 3x + 3 \\ - 8x - 5x + 3x = - 10 + 3 - 1 + 12 \\ - 10x = 4 \\ x = - \frac{4}{10} = - \frac{2}{5} [/tex]
14. Solve the equation. 1. x - 3 = 5 2. 2x + 6 = 10 3. 5x = 12 - x 4. 2x - 4 = x + 1 5. 7x + 12 = 36 + x
Jawaban:
x - 3 = 5
x = 5 + 3
x = 8
2x + 6 = 10
2x = 10 - 6
2x = 4
x = 4/2
x = 2
5x = 12 - x
5x + x = 12
6x = 12
x = 12/6
x = 2
2x - 4 = x + 1
2x - x = 1 + 4
x = 5
7x + 12 = 36 + x
7x - x = 36 - 12
6x = 24
x = 24/6
x = 4

17. [+50](4/10)1.) 5x + 5 = 202.) 30x + 5 = 85solve x ≈
Jawaban:
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
30x + 5 = 85
30x = 85 - 5
30x = 80
x = 80/30
x = (80 ÷ 10)/(30 ÷ 10)
x = 8/3
5x + 5 = 20
5x = 15
x = 15 ÷ 5
x = 3
[tex]\sf ↓ ↓ ↓↓[/tex]
30x + 5 = 85
30x = 80
