Find 3y + 7
Given 2y - 1 = 9, find 3y + 7.
Let's first solve 2y - 1 = 9 for y.
2y - 1 = 9
2y = 9 + 1
2y = 10
y = 10/2
y = 5
Now that we know the value of y, we plug 5 for y in the binomial 3y + 7.
Let y = 5
3y + 7
3(5) + 7
15 + 7 = 22
Answer is 22.

Of course, this question is a review of basic math. Some questions will be harder than others.
