4x=2x+10 - Move constant to the right-hand side and change its sign
4x-2x=10 - Move variable to the left-hand side and change its sign
2x=10 - Combine like terms and divide both sides by 2
x=5 - Answer
Hope this helps!!!
Answer:
it is number 4 why because
Answer:
they are congruent
Step-by-step explanation:
2x - y = 2
<u>6x - y = -2</u>
<u>-4x</u> = <u>0</u>
-4 -4
x = 0
2x - y = 2
2(0) - y = 2
0 - y = 2
<u>+ 0 + 0</u>
<u>-y</u> = <u>2</u>
-1 -1
y = -2
(x, y) = (0, -2)
