Answer:
2x + y = 5
y = 4x – 1
Substitute (2, 1) into system, then:
2x + y = 5 => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)
y = 4x– 1 => 4 x 2 - 1 = 1 => -7 = 1 (not satisfied)
=> Option 3 is correct.
Hope this helps!

Step-by-step explanation:
For # 9, the answer is 4 pants and 11 shirts, see in the comments for my explanation
We need to find surface area, so we can imagine breaking it up into face net.
There will be 18 × 18 square base, four 18 × 40 rectangles, and four triangles with base 18 and height 13.
So the surface area would be sum of these areas.
That would be 18×18 + 4( 18 × 40 ) + 4( (1/2) 18×13 ) = <span>3672
Final answer: 3672 m</span>²
Hope this helps.
