Solve the system of equations.

x + 3y = −1
2x + 2y = 6

Question

Solve the system of equations.

x + 3y = −1
2x + 2y = 6

anonymous · Answer

You can solve it by elimination

anonymous · Answer

double the top equation so 2x+6y=-2
now subtract the second equation from that to only have y in the equation and solve for y, then apply the y value to any of the first 2 equations to solve for x.

anonymous · Answer

You can divide the second equation by -2 
x cancels and you have 
y= -4
 plug in y to find x

anonymous · Answer

and you have solved through elimination

anonymous · Answer

Thats new, I don't think I have actually ever used division for elimination in simultaneous equations *-*
