2 (4x + 7) - 3 (2x - 4) ?

2x + 26

Step-by-step explanation:

Step 1: You need to expand your problem by distributing terms.

8x + 14 - 3 (2x - 4)

Step 2: Then, expand by distributing terms. (again)

8x + 14 - (6x - 12)

Step 3: Next, remove parentheses.

8x + 14 - 6x + 12

Step 4: then, you need to combine like terms.

(8x - 6x) + (14 + 12)

Step 5: Simplify and you're done!

2x + 26
