Answer:
x = 3
Step-by-step explanation:
First, simplify by subtracting 2x from 6x:
6x - 2x + 8 = 20
4x + 8 = 20
Then, solve for x:
4x + 8 = 20
4x = 12
x = 3
So, the answer is x = 3
Multiply 2nd equqation by -1 and add to first
5x+4y=22
<u>-3x-4y=-10 +</u>
2x+0y=12
2x=12
divide by 2
x=6
sub back
3x+4y=10
3(6)+4y=10
18+4y=10
minus 18 both sides
4y=-8
divide by 4
y=-2
(x,y)
(6,-2) is solution
