You can put this solution on YOUR website! Simplify the second equation first. Substitute from the first equation next. Now solve for x, and use it to evaluate y, again using the first equation.

It says to solve the following System of equations by either addition or substitution??
y=-3x+8
4x-2y=14
y = - 3x + 8_____3x + y = 8 ------ eq (i)
4x - 2y = 14_____2(2x - y) = 2(7)_____2x - y = 7 ------ eq (ii)
5x = 15 ------- Adding eqs (ii) & (i)
x = , or
y = - 3(3) + 8 ------- Substituting 3 for x in eq (i)
y = - 9 + 8
You can do the check!!
