Answer:
80
Step-by-step explanation:
180-100=80
Answer:
x=-1 y=2
Step-by-step explanation:
Use Elimination or Substitution (Elimination shown below)
6x+5y=4
6x-7y =-20 <- Multiply by -1
-6x+7y=20
12y = 24
y=2
Plug back into either of the equations and solve for x.
6x + 10= 4
6x = -6
x = -1
Double check work:
-6+10 = 4
Answer:
-40
Step-by-step explanation:
(5x-13)=-8x then- 8x×5 =-40
