Answer:
your answer is 10/3 (fraction)
Step-by-step explanation:
120-40=80
4 x 6=24
80/24=
- first divide both sides by four and get 20/6
- then divide by 2 to get 10/3 (fraction form)
The easy thing to do is eliminate x by subtraction
x + 7y = 24
- x - 9y = -24
-------------------
16y = 48
now solve for y and then substitute the value into either original equation to find x
