Answer:

x=41

y=139

Step-by-step explanation:

x+y = 180 since they form a straight line

y is 3x +16

y = 3x +16

Replace y in the first equation

x+3x +16 = 180

Combine like terms

4x +16 = 180

Subtract 16 from each side

4x+16-16 =180-16

4x =164

Divide each side by 4

4x/4 =164/4

x = 41

y = 3x +16

y = 3*41 +16 = 123+16 =139

Simplify the expression -3x+5y-2+7x-8y+5

Natasha2012 [34]

To simplify this expression we need, at first, to find like terms.

-3x+5y-2+7x-8y-3x+5 = (-3x+7x)+ (5y-8y) -2+5 = 4x + 3y +3

4x + 3y +3 is the answer.
