Question

What is the value of z?



53=−19z+5+7z

Answer 1

-4

Explanation:

53 = -19z+5+7z

53 = -12z+5 | -5 (on both sides)

48 = -12z | :(-12)

z = -4

Answer 2

z=-4

Explanation:

`53=-19z+5+7z`

To solve for z, we need to get z alone

First we combine like terms

-19z +7z is -12z

`53=-19z+5+7z`

`53=-12z+5`

Subtract 5 from both sides in order to eliminate 5

`48=-12z`

Divide both sides by -12 in order to eliminate -12

z= -4

The value of z is -4
