    So solve 5x+2(x+1)=7

    From there combine like terms and then solve for x

    divide 7 by both sides for 7x=5 then you got the x value

    5x+2y=7 y=1+x Substitute the value for y in the first equation 5x+2(1+x)=7 Now Distribute and Combine like terms 5x+2x+2=7 -2 -2 7x=5 /7 /7 x=5/7 Now substitute the value of x in the any equation to find y
