![]() Tenth step: You need common denominators to add fractions so change "9" to "27/3".Ī system of equations is. Seventh step: Divide both sides by (-3/2).Įighth step: Plug -11/3 in as "y" for the first equation. ![]() Sixth step: Subtract (5/2)y from both sides to isolate "y". Third step: In order to make the equation only have one variable, you substitute the second equation in for "x". Second step: You'd want to isolate the y in the first equation so you'd divide by 2 on both sides. Therefore, you can move the -9 in the first equation to the other side. This question isn't exactly the ideal question to use substitution but here:įirst step: You have the "x" variables isolated in both equations but you only need it to be isolated in one equation. ![]()
