7x+49=7x+49
Use the distributive property to multiply 7 by x+7.
7x+49-7x=49
Subtract 7x from both sides.
49=49
Combine 7x and -7x to get 0.
\text{true}
Compare 49 and 49.
x\in \mathrm{C}
This is true for any x.
7x+49=7x+49
Use the distributive property to multiply 7 by x+7.
7x+49-7x=49
Subtract 7x from both sides.
49=49
Combine 7x and -7x to get 0.
\text{true}
Compare 49 and 49.
x\in \mathrm{R}
This is true for any x.
