 x + y =-2
2x-3y=9

campbell_st · Answer

multiply the 1st equation by 3, add to the 2nd equation to eliminate y. Solve for x. Substitute x back into either equation to find y

Can you do the math to in steps ? what's the answer ? @campbell_st

campbell_st · Answer

triple the 1st equation 

3x + 3y = - 6
2x - 3y = 9               add the 2 equations
------------
5x = 3

now solve for x

the substitute the value of x into either equation to find y

and can you check the 1st equation is = -2.....
