The answer is a because it is saying the corrext answer to the question
2x-y=4
Therefore: y=2x-4
---------------------------------
5x-10/4(2x-4)=10
5x-5/2(2x-4)=10
5x-5x+10=10
10=10

Answer:
Step-by-step explanation:
7 no
113+12x+7+90+90=360
300+12x=2=360
12x=360-300
x=60/12
x=5
9 no
10x-6+109+79+20x-2=360
30x+180=360
30x=360-180
x=180/30
x=6
The answer to this is 143".
