4a+12=12+4a
Use the distributive property to multiply 4 by a+3.
4a+12-4a=12
Subtract 4a from both sides.
12=12
Combine 4a and -4a to get 0.
\text{true}
Compare 12 and 12.
a\in \mathrm{C}
This is true for any a.
4a+12=12+4a
Use the distributive property to multiply 4 by a+3.
4a+12-4a=12
Subtract 4a from both sides.
12=12
Combine 4a and -4a to get 0.
\text{true}
Compare 12 and 12.
a\in \mathrm{R}
This is true for any a.
