Question

Solve each system by elimination
4x-9y=61
10x+3y=25

Answer 1

If you multiply the bottom equation by 3, then add the two equation together, you will remove y and can solve for x, then plug x in and solve for y.

Answer 2

i get a really big decimal for x.

Answer 3

Care to share your equations, something isn't right.

Answer 4

30x+9y=61
4x-9y=61
34x=86
x=?

Answer 5

ohhhh, i see my mistake. x=4?

Answer 6

\[[10x + 3y = 25] \times 3 \rightarrow 30x + 9y = 75\]

4x - 9y = 61
+30x + 9y = 75

Answer 7

Yep you got it.
