5x - 3x = 2 +7

2x = 9

Then to find x, divide 9 by 2

x = 4...

Solve the inequality 3x ≤ 4x+5

So I would begin by minusing 5 from both sides and that will give you 3x - 5 ≤ 4x. Then we want to gather our x's onto one side, so I would '-3x' from both sides which leaves you with - 5 ≤ 4x - 3 x, s...
