Find x and y in 2x+2y=124x_4y=13
2 answers:
Answer:
x = 4.625, y = 1.375
Step-by-step explanation:
I am assuming that the second equation is 4x - 4y = 13.
2x+2y=12
4x-4y=13
Multiply first equation by -2:-
-4x - 4y = -24 Add this to the second equation to eliminate x:-
-8y = -11
y = 11/8 = 1.375
Plugging this into the first equation:-
2x + 2(1.375) = 12
2x = 9.25
x = 4.625
For the first one the answer is y=-1x+6 which means x=-1 and y=6

Answer:
The solutions are given below:
Step-by-step explanation:
x(x-3)+4(x²+2)
= x²-3x+4x²+8
= x²+4x²+8-3x
= 5x²+8-3x
2(a+5)-3(a+7)
= 2a+10-3a-21
= 2a-3a+10-21
= -a-11
xy(x²yz-xy²z+xyz²)
= x³y²z-x²y³z+x²y²z²
-4(a²-2a+8)
= -4a²+8a-32
