y=−40
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4−y5=2−2y8
4+−15y=2+−14y
−15y+4=−14y+2
Step 2: Add 1/4y to both sides.
−15y+4+14y=−14y+2+14y
120y+4=2
Step 3: Subtract 4 from both sides.
120y+4−4=2−4
120y=−2
Step 4: Multiply both sides by 20.
20*(120y)=(20)*(−2)
Answer:
y=−40
Answer:
y= -40
Step-by-step explanation:
4 - y/5 = 2 - 2y/8
4 - y/5 = 2 - y/4
4 x 20 - y x 20/5 = 2 x 20 - y x 20/4 (reduce the fractions)
4 x 20 - 4y = 2 x 20 - 5y
80 - 4y = 2 x 20 - 5y
80 - 4y = 40 - 5y
-4y + 5y = 40 - 80
y = 40 - 80
y = - 40
