Answer:

Step-by-step explanation:

Add the 3/4 to cross it out on the left side and whatever you do to one side you do to the other side. so you add 3/4 or .75 on to 10 to get 10.75.

k-3/4=10

k=10.75

Subtract the 5/7 from the Z and subract it from -3 to get, -3.71.

Z+5/7=-3

Z=3.71

Subtract 9 from the left side and subtract 9 from the right side.

9+t/12=-3

t/12=-12

Then you would multiply by 12 from the left side and multiply by 12 from the right side.

t/12=-12

t=-144
