I think it’s C. If you turn them both the same way, they look to be around the same size.
7x-4=5x+15
-5x on both sides
2x-4=15
add four to both sides
2x=19
divide both sides by 2 to isolate x
x=9.5
Plug in -2 for y then solve for x. The answer should be x= -2
1. change the fractions into decimals- 3/4=0.75 1/4=0.25
2. 2 x 0.75= 1.50
3. 1.50-0.25=1.25
answer- 1.25
