Question
Solve the equation
y=−215
Alternative Form
y=−7.5
Evaluate
−140=18+4(5y−2)
Swap the sides of the equation
18+4(5y−2)=−140
Move the expression to the left side
18+4(5y−2)−(−140)=0
Subtract the numbers
More Steps
Evaluate
18−(−140)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
18+140
Add the numbers

Calculate
4(5y−2)
Apply the distributive property
4×5y−4×2
Multiply the numbers
20y−4×2
Multiply the numbers
20y−8
158+20y−8
Subtract the numbers
150+20y
150+20y=0
Move the constant to the right-hand side and change its sign
20y=0−150
Removing 0 doesn't change the value,so remove it from the expression
20y=−150
Divide both sides
2020y=20−150
Divide the numbers
y=20−150
