What is the solution of the system? Use substitution. 2x - y = -7 and 4x- y = -4 (–1.5, 4) (1.5, 10) (4, –1.5) (–1.5, –2) 2. What is the solution of the system? Use elimination 5x +7y = 32 and 8x +6y = 46 (8, 5) (1, 5) (7, 0) (5, 1)

\[2x - y = -7 \]\[ 4x- y = -4\]Rearrange the first equation to solve for y, then substitute into the second sentence for y. Then solve for x.
I got (1.5, 10) and (8,5) but i dont think they are right
