X+2(x+y)=7 3(x-y)=1-2y What is x&y???? Please answer asap!!!!

Shkiper50 [21]

X= -x over 2 (negative x as a fraction and 2 is the denominator) minus y+ (seven as the numerator over 2 as the denominator).
Solve for y by simplify both sides with inverse operations, then isolate the variable and you get, y = 3x - 1.
