Answer:
Step-by-step explanation:
<u>Given system of linear equations:</u>
<u>Add up the equations to eliminate y:</u>
- x + 2x = 90 + 105
- 3x = 195
- x = 65
<u>Find y:</u>
- y + 65 = 90
- y = 90 - 65
- y = 25
Answer:
F (4, 2) G (2, 2) H (0, -4)
Step-by-step explanation:
P = 2L + 2W
P = 2(6x - 2) + 2(x - 1)
P = 12x - 4 + 2x - 2
P = 14x - 6
