3 (y - 1) + 2 (y + 3) = 13

y=2

Step-by-step explanation:

3 (y - 1) + 2 (y + 3) = 13

3y-3+2y+6=13

5y+3=13

5y=10

y=2

y = 2

Step-by-step explanation:

Although it's rather obvious that we're to solve for y here, you should include those instructions with the problem.

Carrying out the indicated multiplication yields:

3y - 3 + 2y + 6 = 13.

Grouping the y terms, we get 5y on the left side; grouping the constants, we get 10 on the right side.

Dividing both sides of 5y = 10 by 5, we get the final answer, y = 2.
