Need help myself not sure sorry
If -2 (s - 7) > 4s + 8
then -2s + 14 > 4s + 8
14 - 8 > 4s + 2s
6 > 6s
∴ <span>all real numbers s such that -2(s - 7) > 4s + 8 are s < 1</span>
Answer:
x=12, y=-3
Step-by-step explanation:
Plug (-4y) in for x in the top equation. The equation will now read 2(-4y) + 7y = 3. Distribute the 2 into the perenthecies getting: -8y+7y=3. -8+7 is -1 giving -y+3. Divide by -1 making y = -3. Plug -3 back into the top equation and solve for x: 2x + 7(-3)=3. 2x-21=3. 2x=24. x=12.
