Question

6x=1/2(2X +7)
Solve for x

Answer 1

Explanation:

6x=1/2(2x +7) Multiply both sides by 2

2*6x = 1/2(2x + 7)*2

12x = 2x + 7 Subtract 2x from sides

12x-2x =2x-2x+7

10x = 7 Divide by 10

x = 7/10

x = 0.7

Let's check it

6(0.7) = 4.2

1/2 (2*0.7 + 7)

1/2 (1.4 + 7)

1/2 ( 8.4)

4.2

Both sides check. The answer must be x = 0.7
