Tao wants to check that the expression 3(4x – 6) simplifies to 12x – 18. what is the value when 2 is substituted for x into both expressions?

Keywords:

Equation, simplified, variable, compare

For this case, we have an equation of the form, where . The equation was simplified and we want to find the value ofwhen the variable and compare the result of both equations. So:

(1)

We apply distributive property to simplify, taking into account that:

(2)

If , we substitute in the original equation and in the simplified equation:

1)

2)

Thus, when is substituted in both expressions, the result is 6.

For and , substituting we have the result is 6.
