Solve each system of equations by using substitution.
x+4y=3
2x-3y=17

X+4y=3  subtract 4y from both sides

x=3-4y

2x-3y=17, using x found above becomes:

2(3-4y)-3y=17 perform indicated multiplication on left side

6-8y-3y=17  combine like terms on left side

6-11y=17  subtract 6 from both sides

-11y=11  divide both sides by -11

y=-1, using this y in x+4y=3 becomes:

x+4(-1)=3

x-4=3  add 4 to both sides

x=7

So the solution to the system of equation is the point (7, -1)
