Solve the equation
v=3
Evaluate
4v−20=−4(v−1)
Expand the expression
More Steps
Evaluate
−4(v−1)
Apply the distributive property
−4v−(−4×1)
Any expression multiplied by 1 remains the same
−4v−(−4)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−4v+4
4v−20=−4v+4
Move the expression to the left side
4v−20+4v=4
Move the expression to the right side
4v+4v=4+20
Add and subtract
More Steps
Evaluate
4v+4v
Collect like terms by calculating the sum or difference of their coefficients
