This is a system of linear equations. First, you can add the two equations together to eliminate the y so that you can solve for x:
-5x + -7x = 0 + -96
-12x = -96
x = 8
Use x to solve for y:
-5 * 8 + 8y = 0
Add 40 to both sides and divide by 8:
y = 5
So, x = 8 and y = 5.
Answer:
x = 17.2
Step-by-step explanation:
since they are supplementary, when you add then together they equal 180
4x + 8 + 6x = 180
Combine like terms
10x + 8 = 180
subtract 8 from both sides
10x = 172
divide each side by 10
x = 17.2

14-5+20÷2∧2+4
exponent first: 14-5+20÷4+4
Divide: 14-5+5+4
Solve left to right: 9+5+4
add all: 14+4 = 18
