4x - 4y = -4
- (4x + y = 16)
___________
5y = -20
Now on solving the equation we have:
= 5y = -20
= y = -20/5
= y = -4
If y = -4 then,
= 4x + y = 16
= 4x + (-4) = 16
= 4x = 16 + 4
= x = 20/4
= x = 5
Thus, x = 5, y = -4
Answer:
I have no idea
Step-by-step explanation:
but here is thisss
X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.
