Question

How do we check an answer to an algebraic equation to make sure that it is correct?

Answer 1

Determine whether a number is a solution to an equation.

• Substitute the number for the variable in the equation.
• Simplify the expressions on both sides of the equation.
• Determine the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.

Answer 2

Answer:

substitute the value you solve the variable for back into the original equation and see if the left and right sides of the equation are equal

Step-by-step explanation:

let's say you have this equation:    

2x - 10 = 26

solve by first adding 10 to each side to get:

2x = 36

now divide each side by 2 to get:

x = 18

to check, substitute 18 in for 'x' in the original equation to see if the left side equals the right side of the equation:

2(18) - 10 = 26

36 - 10 = 26

26 = 26

we know our answer is correct
