For this one you want to cancel out the x-terms.
Multiply top equation by -2
---> -2x -10y = 6
---> 2x +7y = 3
Add them together
---> -3y = 9
Solve for y ...

Answer:
160,000 Nm
2667 Nm/sec
Step-by-step explanation:

Answer: x ≤ 10
Step-by-step explanation:
20 + 13x ≤ 150
13x ≤ 150 - 20
13x ≤ 130
x ≤ 130 ÷ 13
x ≤ 10
