got it right on edjenuity
Let the first number be x and decide number be y
therefore x+y = -42
also. x-y = 52 using the process of elimination
we get: 2x = 10
we divide both sides by 2, which gives us x=5
then we substitute the value of x in the first equation
that gives us. 5+y = -42
thus. y = -47
Supplementary angles measure 180°. Make an equation:

Subtract 28 to leave the variable in the parentheses alone:

Add the 2 x's together:

Your new equation is:

Divide both sides by 2 to leave the variable alone

The supplement measures 76°
