4(x+x+7)-2x+8-4
Substitute x with 1
4(1+1+7)-2(1)+8-4
=4(2+7)-2+4
=4(9)-2+4
=36-2+4
=34+4
=38
4(x+x+7)-2x+8-4
Substitute x with 2
4(2+2+7)-2(2)+8-4
=4(4+7)-4+4
=4(11)
=44. Hope it help!

Answer:
4.14
Step-by-step explanation:
the orange is 1 pound
the green is 0.1 pound
the blue is 0.01 pound
3 orange is 3
11 green is 1.1
4 blue is 0.04
3+1.1+0.04=4.14
hope that made sense
6x=120-5y -> x=20-5/6*y -> 7(20-5/6*y) + 11y =202 -> 140-35/6*y + 11y = 202 -> 140+31/6*y=202 -> 31/6*y = 62 -> y = 12.
