Answer:

2x-7=13 X=10

3x+4=25 X=7

2/3x=8 X=12

3/2x=6 X=4

Step-by-step explanation:

Answer:

a. x = 12

b. x = 4

Step-by-step explanation:

a.  [tex]\frac{2x}{3}=8[/tex]

Multiply both sides by 3;

[tex]\frac{2x}{3} *3=8*3\\\\2x=24[/tex]

Divide both sides by 2;

x = 12

b.  [tex]\frac{3x}{2}=6[/tex]

Multiply both sides by 2;

[tex]\frac{3x}{2}*2=6*2\\\\3x=12[/tex]

Divide both sides by 3;

x = 4
