Question

`2(4x + 5) > 7x + 20`

Answer 1

First, distribute 2 to all terms within the parenthesis

2(4x + 5) = 8x + 10

8x + 10 > 7x + 20

Isolate the x. Treat the > like a equal sign. Subtract 7x and 10 from both sides

8x (-7x) + 10 (-10) > 7x (-7x) + 20 (-10)

Simplify

8x - 7x > 20 - 10

x > 10

x > 10 is your answer

hope this helps
