Question

Solve the system of equations. -2x + 3y = 8
3x – y = -5

Answer 1

multiply second equation by 3
add the two together

Answer 2

Try this:
Multiply the second by 3.
Add it the the first one.
tell us what do you get.

Answer 3

how do i set that up?

Answer 4

Like this:
1st :-2x+3y=8
2nd*(3) : 9x-3y=-15

Answer 5

Now add them.
Tell us what do you get.

Answer 6

\[-2x + 3y = 8\]\[ 3x – y = -5\]

\[-2x+3y=8\]\[3(3x-y)=3(-5)\]
\[-2x+3y=8\]\[9x-3y=-15\] add to get \[7x=-7\]solve for \(x\)\[7x=-7\implies x=-1\]

Answer 7

y=3x+5
Substitute this value in eq 1

Answer 8
