You want to use the substitution property here.

Get the first equation to get as to an "x=..." or "y=..."

So, rewrite the first equation to be in slope-intercept form. y= -x+4

Substitute this equation in on the second equation

2x-(-x+4)=5

Simplify:

3x+4=5

3x=1

x=1/3

Now plug in your answer on one of the original equations.

(1/3) + y = 4

y = 4 - (1/3)

y = 3

Therefore:

x = (1/3)

y = 3
