Solve the equation.
5u - 10 = 70

u = 16

Step-by-step explanation:

5u - 10 = 70

Add 10 to each side

5u -10 +10 = 70+10

5u = 80

Divide each side by 5

5u/5 = 80/5

u = 16

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

it's equivalent, so we can say that its equal.

90 = 3x

x = 90/3

x = 30

so:
