Question
Solve the equation
a=2
Evaluate
3(a−5)−6=−15
Move the expression to the left side
3(a−5)−6−(−15)=0
Subtract the terms
More Steps
Evaluate
3(a−5)−(−15)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
3(a−5)+15
Rewrite the expression
3a−15+15
Since two opposites add up to 0,remove them form the expression
3a
3a−6=0
Move the constant to the right-hand side and change its sign
3a=0+6
Removing 0 doesn't change the value,so remove it from the expression
3a=6
Divide both sides
33a=36
Divide the numbers
a=36
