Answer:
x+ y = 7
Step-by-step explanation:
given equation = x+y,2x+2y=14
we know that the form of linear equation in two variable is ax +by= c
it is in the form of above equation
so , we can write the above form in ax+by-c =0
thus x+y-7=0, 2x+2y-14=0
to solve x+y-7=2x+2y-14
=-7+14=2x+2y-x-y
7 =2x-x+2y-y (like terms)
7=x+y
hence (x+y) =7
