7y+1 given -2y+6=2

Question

Need help breaking this problem what is the value of Y I came up with

Answer 1

Hi Jose,

First you will need to solve the equation to find the value of y. Then substitute this value into the expression 7y + 1 to find the value of the expression.

Solve the equation:

-2y + 6 = 2

-2y + 6 - 6 = 2 - 6

-2y = -4

-2y/-2 = -4/-2

y = 2

Now substitute y = 2 into the expression 7y + 1:

7y + 1 = 7 • 2 + 1 = 14 + 1 = 15

The expression is equivalent to 15 when y = 2
