Subtract 6 from both sides so you have -4x=3x-42 then subtract 3x from both sides to get -7x=-42 lastly divide negative 7 from both sides to get x=6

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

-4x + 6 = 3x - 36

Step 2: Solve for x

Add 4x to both sides: 6 = 7x - 36
Add 36 to both sides: 42 = 7x
Divide both sides by 7: x = 6

Step 3: Check

Plug in x to verify it's a solution.

-4(6) + 6 = 3(6) - 36

-24 + 6 = 18 - 36

-18 = -18

4 - x + <img src="https://tex.z-dn.net/?f=6%5E%7B2%7D" id="TexFormula1" title="6^{2}" alt="6^{2}" align="absmiddle" class="latex

Answer:

x ≤ 19

Step-by-step explanation:

The instructions here are probably "solve for x." Please include them.

4 - x + 6^2 ≥ 21

becomes 4 - x + 36 ≥ 21

Now combine like terms. 4 and 36 combine to 40: 40 - x ≥ 21, and so:

19 - x ≥ 0

Adding x to both sies results in

x ≤ 19

Please, include the instructions when you post a question. Thanks.
