1. Solve by using the Elimination method for solving systems of equations.
2. Top equation, minus, the other equation on the bottom. (4x-9y=-21)-(4x+3y=-9)
3. Subtract like terms.
4x-4x = 0
-9y - 3y = -12y
-21 - -9 = -30
4. Isolate for y
y= -30/-12 =5/2
5. Plug the value of y into original equation and isolate for x.
