Solve this system of equations using the addition/elimination method. 5x-2y=-10 3x-6y=66
Multiply each equation by the value that makes the coefficient of y equal. Do this by dividing the least common multiple of the coefficient of y by the current coefficient. The least common multiple is 6.
Then add the two equations together to eliminate y from the system.
Finally, substitute the value found for x into the original equation to solve for y.
