The equation 7(u-5)=21 is solved in several steps below. For each step, choose the reason that best justifies it.
krok68 [10]

Answer:

u = 8

Step-by-step explanation:

The steps are not shown. So, I will solve from scratch

Given

7(u -5) = 21

Required

Solve, with steps

7(u -5) = 21

Apply distributive  property

7u - 7 * 5 =21

7u - 35 =21

Collect like terms

7u = 35 + 21

7u = 56

Divide both sides by 7

\frac{7u}{7} = \frac{56}{7}

u = 8
