inequality help? MEDAL

−4(x + 8) + 25 ≤ −2 + 1(x − 50)
−4x − 32 + 25 ≤ −2 + 1x − 50
−4x − 7 ≤ 1x − 52
−5x ≤ −45
x ≤ 9

Answer 1

where did the dude mess up?

Answer 2

When you divide by a negative in an inequality you need to switch the direction the inequality is facing so the very last step dividing -5x by -5 should switch the inequality so your answer should be: x=>9

Answer 3

when you divide or multiply both side by negative number you must have to flip sign
