Question

I need help with number 5

Answer 1

-6 is the answer.

Explanation:

4x - 5 = x - 23

or, 4x - x = -23 + 5

or, 3x = -18

or, x = -18/3

therefore, x = -6

Answer 2

the answer is (3)

Explanation:

4x - 5 = x - 23

i) bring -5 to the right-hand side and change its sign

4x = x - 23 + 5

ii) calculate the value

4x = x - 18

iii) bring x to the left-hand side and change its sign

4x - x = -18

iv) calculate the value

3x = -18

v) divide both sides of the equation by 3

`(3x)/(3) = ( - 18)/(3)`

`x = - 6`
