Question 1189820
two equations need to be solved simultaneously.


2y = 2x + 6
y = 2x + 4


multiply both sides of the second equaion by 2 and leave the first equation as is to get:


2y = 2x + 6
2y = 4x + 8


subtract the first equation from the second to get:


0 = 2x + 2


solve for x to get x = -1


replace x in y = 2x + 4 to get y = -2 + 4
solve for y to get y = 2


you have x = -1 and y = 2


replace x and y in both original equations to get:


2y = 2x + 6 becomes 4 = -2 + 6 which becomes 4 = 4.
y = 2x + 4 becomes 2 = -2 + 4 which becomes 2 = 2.


this confirms the values are good.


your solution is that x = -1 and y = 2.
since the first variable is y, then your solution would becomes y = 2.
