Question

7. If 26y - 4 = 68 + 2y , then y=?

Answer 1

y = 3

Explanation:

We move all terms to the left:

26y-4-(68+2y)=0

We add all the numbers together, and all the variables

26y-(2y+68)-4=0

We get rid of parentheses

26y-2y-68-4=0

We add all the numbers together, and all the variables

24y-72=0

We move all terms containing y to the left, all other terms to the right

24y=72

y=72/24

y=3
