Answer:
-11x + 7y = 20
Step-by-step explanation:
See image. Multiply
2(-2x + 2y = 16)
You get -4x + 4y = 32
Then line that guy up underneath the
-15x + 3y = -12. You're adding vertically from the top down, x's with x's and y's with y's and plain numbers with plain numbers. See image
Answer:
6 & 10
Step-by-step explanation:
x+6>10
x>4
x<10+6
x<16
There will only be one solution to this problem.
220 = 2x - 12x
Combine like terms on the right side of the equation:
220 = - 10x
Divide both sides by - 10 to isolate the variable x.
220 / - 10 = x
-22 = x, one solution.
