EVALUATE: solve

SIMPLIFY (in this case): find the simplest form of the expression, meaning you have to combine like terms

123 - 2x - 3x + 7       this is the original equation

To make it easier: spread apart the terms and add them together like so:

123 & 7

-2x & -3x

Add them together to get

130 - 5x THIS IS THE SIMPLEST FORM OF THE ORIGINAL EXPRESSION

Now, evaluate the expression when x equals 5, meaning you should substitute x for 5 wherever you see an x.

130 - 2 (5)

130 - 10

120 THIS IS THE VALUE OF THE EXPRESSION (ur second answer)
