Simplifying algebraic expressions

-2x + 7(9x - 8)

Hey there, let's solve this step by step

1) Distribute 7(9x - 8), by multiplying (7)(9x) + (7)(-8)
-2x + 7(9x -8)
-2x + 63x -56

2) We want to combine like terms. Since -2x and 63x are like terms, we want to combine those
-2x + 63x - 56
61x - 56

Since 61x and 56 are incompatible, we cannot combine them, therefore that is our final answer : 61x - 56
