Answer:

y=4/3

x= -37/3

Step-by-step explanation:

Is this a substitution equation? If so, divide the second equation by 1/2 to get 1/2x+7.5=y. Then I plugged it in to get -x+1/2(1/2x+7.5)=13

After simplifying, I got -x+1/4x15/4=13, then simplifying once more to get -3/4x=37/4

The final answer I got for x was -37/3, which I plugged into the original equation to get y=4/3

*cough cough* i probably got this wrong feel free to check i spent like 15 minutes on this ;-; wowee
