angles 3(14)-7 and 15y-5 are supplementary

Question

solve for y

Answer 1

To solve for y, we need to set the sum of the two angles equal to 180 degrees, since supplementary angles add up to 180 degrees.

So, we have the equation:

3(14) - 7 + 15y - 5 = 180

Simplifying the left side of the equation, we have:

42 - 7 + 15y - 5 = 180

Combine like terms:

30 + 15y = 180

Subtract 30 from both sides of the equation:

15y = 150

Divide both sides by 15 to solve for y:

y = 10

Therefore, the value of y is 10.
