Answer 3

You have already solved systems of linear equations. I expect that you'll apply what you learned earlier to solve this new system. Please share your initial efforts to solve this system BEFORE you ask for help.

Answer 4

Multiply the 2nd equation by -2. Show your work, please.

Now combine this new 2nd equation with the 1st equation. Show your work.

Now solve for y.

Answer 5

This approach is called "elimination by addition / subtraction."

Answer 6

Solve equation [2] for the variable h
Plug this in for variable h in equation [1]Solve equation [1] for the variable g

Use the g value to solve for h

Answer 7

when i worked out the problem I got the answer C. and this problem is just like the last one but before u try to solve it find out the decimals for the fractions

Answer 8

Yes, ilianapaulk's approach will also work fine. It's called "elimination by substituion."

Answer 9

I agree ^^^

Answer 10

Dope: If you've worked out this problem, then make suggestions to animal lover regarding what to do. But don't give her your solution outright.

Answer 11
