Answer 1

Explanation:

The second equation shows the makeup of y. Put that value for y into the first equation.

-2x + 5(3x + 13) = 13 Remove the brackets.

-2x + 15x + 65 = 13 Subtract 65 from both sides

-2x + 15x = 13 - 65 Combine both the left and right.

+13x = - 52 Divide by 13

x = - 52 / 13

x = - 4

3x + 13 = y

3*(-4) + 13 = y

-12 + 13 = y

y = 1
