Question

Find the value of x.

Answer 1

sorry i didn't find the value of x, but i did find the value of y. if that helps.

Explanation:

y=a+5

Answer 2

x = 19

Explanation:

The sum of both angles will be equal to a supplementary angle. A supplementary angle is when two angles add up to be 180°. Write an equation and solve for x.

3x + 5 + 7x - 15 = 180

~Combine like terms

10x - 10 = 180

~Add 10 to both sides

10x = 190

~Divide 10 to both sides

x = 19

Best of Luck!
