Answer:
3,520
Step-by-step explanation:
Okay. First simplify all the like terms (all the coefficients and all the variables).
When simplified it should give you:
5x-11
Answer:
y = 11
Step-by-step explanation:
Perimeter = 6 + 5y + y + 2 + 4y + 3
= 10y + 11
10y + 11 = 121
10y = 121 - 11
= 110
y = 110 ÷ 10
y = 11
