Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
Answer:
Use the formula of areal*b*h
D. X=18
Exp:
16-X=-2
-16 -16
-X=-18
X=18
Do you mind writing out the equation/question deal-o it might help us all some.
Answer:
t = -6.25
Step-by-step explanation:
3/4 (184+t) =237
multiply by 3/4
184 + t = 177.75
