Solve these systems of equations using any method. Check each solution, if possible. Homework Help ✎
One strategy to solve this system of equations is to multiply the bottom equation by −1 so you can eliminate.
2x + 3y = 9
3x − 3y = 6
5x = 15
After finding x, plug in its value into one of the equations to find the value of y.
x = 3
y = 1
Because one of the equations above is already solved for x, one strategy to solve this system is to substitute the first equation in for x in the second equation.
Use the Equal Values Method.
Refer to part (a).
x = −4; y = 5
