One method of solving a system of equations like this is substitution, since they give you an equation that is simply y. Take y=-x+4 and plug it into the first equation given, then solve for x: 4x+3(-x+4)=13 I'll let you work it out the rest of the way, but after you get x just plug that value into either one of the equations and solve for y.

To find x, distribute the 3 and then combine like terms: 4x-3x+12=13 Now get all like terms on the same sides: x=1 Now plug in this value of x to the equation y=-x+4 to get the y value: y=-(1)+4 y=3
