Evaluate
3a+4=3a−2a
Subtract the terms
More Steps

Evaluate
3a−2a
Collect like terms by calculating the sum or difference of their coefficients
(3−2)a
Subtract the numbers
a
3a+4=a
Move the variable to the left side
3a+4−a=0
Subtract the terms
More Steps

Evaluate
3a−a
Collect like terms by calculating the sum or difference of their coefficients
(3−1)a
Subtract the numbers
2a
2a+4=0
Move the constant to the right side
2a=0−4
Removing 0 doesn't change the value,so remove it from the expression
2a=−4
Divide both sides
22a=2−4
Divide the numbers
a=2−4
