Respuesta :
64 - (3y + 8y + y) / 40 = 37
Simplify 3y + 8y + y
64 - 12y / 40 = 37
Add 12y / 40 to both sides and subtract 37
27 = 12y / 40
Multiply both sides by 40
1080 = 12y
Divide both sides by 12
90 = y
Answer:
y=90
Step-by-step explanation:
Collect the like terms first (3y, 8y, and y) and add them together, which gives you 12y. Equation looks like this so far 64-12y/40=37
Divide the -12 by 40, which can be reduced to -3/10.Equation so far: 64-3/10y=37
Multiply each side by 10 to cancel out the 10 in -3/10y. Equation so far: 640-3y=370
Use inverse operations to move the 640 with the 370. Equation so far: 3y=370-640
Subtract 640 from 370, which gives you -270. Then you'll have -3y=-270 and divide both sides by -3.
