Question

-12.2z - 13.4z = -179.2

Answer 1

Answer:

7

Step-by-step explanation:

This is an equation, where we find the value of z. We can simplify the equation.

-12.2z - 13.4z = -179.2

-25.6z = -179.2

Now, to find the value of z, we have to isolate the variable by dividing both sides by -25.6

-25.6/-25.6z = -179.2/-25.6

1z = 7

z = 7
