We have two unknowns from the equation therefore, two equations are needed. These equations are:
<span>
3x + y = 9
y = –4x +10
To solve for y, we first substitute the second equation to the first one.
</span>3x + –4x +10<span>= 9
</span><span>x = 1
We substitute the value of x to either of the equations and solve for y.
</span>y = –4(1) +<span>10
</span><span>y = 6
