Answer 2

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.

Answer 3

hmmm i dunno

Answer 4

Yes, that is a good way to solve this problem.

Answer 5

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
