Answer:
z ≤ 7
Step-by-step explanation:
9x - 7 ≤ 28 + 4x
9x - 4x ≤ 28 + 7
5x ≤ 35
x ≤ 35 / 5
x ≤ 7
Answer:
I'm good at Algebra 2 I've taken it already
Step-by-step explanation:
First of all, expand the left hand side:

Sum like terms:

Add 3 to both sides:

Subtract 3x from both sides:

So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.
