Equation 1) y = 2x + 5
Equation 2) y = -3x - 5
For equation 1, subtract 2x from both sides. For equation 2, add 3x to both sides.
1) -2x + y = 5
2) 3x + y = -5
Subtract equations from one another
-5x = 10
Divide both sides by -5.
x = -2
Plug in -2 for x in the first equation.
y = 2x + 5
y = 2(-2) + 5
Simplify.
y = -4 + 5
y = 1
(-2, 1)
