Answer:
x > -1
Step-by-step explanation:
<u>Step 1: Distribute</u>
3(3x + 7) > 4 - 8(4 + 5x)
(3 * 3x) + (3 * 7) > 4 + (-8 * 4) + (-8 * 5x)
9x + 21 > 4 - 32 - 40x
<u>Step 2: Combine like terms</u>
9x + 21 > 4 - 32 - 40x
9x + 21 > -28 - 40x
<u>Step 3: Add 40x to both sides</u>
9x + 21 + 40x > -28 - 40x + 40x
49x + 21 > -28
<u>Step 4: Subtract 21 from both sides</u>
49x + 21 - 21 > -28 - 21
49x > -49
<u>Step 5: Divide both sides by 49</u>
49x / 49 > -49 / 49
<em>x > -1</em>
Answer: x > -1
