2x+5=3\left(x+7\right)
Variable x cannot be equal to -7 since division by zero is not defined. Multiply both sides of the equation by x+7.
2x+5=3x+21
Use the distributive property to multiply 3 by x+7.
2x+5-3x=21
Subtract 3x from both sides.
-x+5=21
Combine 2x and -3x to get -x.
-x=21-5
Subtract 5 from both sides.
-x=16
Subtract 5 from 21 to get 16.
x=-16
Multiply both sides by -1.
