Question

What is the value of u? u+12=7u

Answer 1

2

Explanation:

u+12=7u

12=6u

2=u

Answer 2

u = 2

Explanation:

u + 12 = 7u

First step is to subtract u from both sides of the equation

u + 12 - u = 7u - u

12 = 6u

This can also be written as,

6u = 12

Next step is to divide the coefficient of u which is 6 from both sides

6u/6 = 12/6

u = 2
