Question

Solve.
3/5x - 7 = 23
A. x = 40
B. x = 45
C. x = 50
D. x = 55

Answer 1

(C) x=50

Explanation:

`(3)/(5 )x -7=23`

`(3x)/(5) -7=23`

`(3x)/(5) -7+7=23+7`

`(3x)/(5)=30`

`3x=30* 5`

`3x=150`

`x=50`

Answer 2

(C) X = 50

Explanation:

(3/5)*x-7 = 23 // - 23

(3/5)*x-23-7 = 0

3/5*x-30 = 0 // + 30

3/5*x = 30 // : 3/5

x = 30/3/5

x = 50 (Sorry if it's wrong)
