Question

Find x from 4x + 5 = 6x - 7 a. 4 b. 5 c. 6 d. 7

Answer 1

c

Explanation:

given the equation

4x + 5 = 6x - 7 ( subtract 4x from both sides )

4x - 4x + 5 = 6x - 4x - 7 ( simplify both sides )

5 = 2x - 7 ( add 7 to both sides )

5 + 7 = 2x - 7 + 7 ( simplify both sides )

12 = 2x ( divide both sides by 2 )

`(12)/(2)` =
`(2)/(2)` x , that is

6 = x
