Answer:
x = 16
Step-by-step explanation:
"Solve algebraically" means "solve it using the rules of algebra." You could also solve it by guessing, or by graphing, or by submitting the equation to a machine solver (calculator, app, or web site).

To solve for x, undo what has been done to x. The expression on the right shows that x has 2 added, and the sum is divided by 3. We "undo" these operations in reverse order.
undo divide by 3
Multiplication is the inverse operation for division, so we want to multiply both sides of the equation by 3:
3(6) = 3(x +2)/3
18 = x +2
undo add 2
Subtraction is the inverse operation for addition, so we want to subtract 2 from both sides of the equation:
18 -2 = x +2 -2
16 = x
The value of x that makes this equation true is x = 16.
