subsitute 6x-11 for y in other equation


-2x-3(6x-11)=-7
distribute
-2x-18x+33=-7
-20x+33=-7
minus 33 both sides
-20x=-40
divide both sides by -20
x=2

I can't figure it out. <br>2x+2y=2<br>-4x+4y=12<br>​
koban [17]

Answer:

how to solve 2x+2y=2 , -4x+4y=12

this is  solving equations using substitution .... i have ALOT more but i juss dnt get this stuff

2x + 2y = 2      -4x + 4y = 12

x + y = 1

x = 1 - y

-4x + 4y = 12

-4(1 - y) + 4y = 12

(-4 + 4y) + 4y = 12

-4 + 8y = 12

8y = 16

y = 2

2x + 2y = 2

2x + 2(2) = 2

2x + 4 = 2

2x = -2

x = -1

Check.

-4x + 4y = 12

-4(-1) + 4(2) = 12

4 + 8 = 12

Answer: x = -1 and y = 2
