Hey there!
n + 4 = 11
SUBTRACT 4 to BOTH SIDES
n + 4 - 4 = 11 - 4
CANCEL out: 4 - 4 because it give you 0
KEEP: 11 - 4 because it help solve for the n-value
NEW EQUATION: n = 11 - 4
SIMPLIFY IT!
n = 7
Therefore, your answer is: n = 7

Answer:
x meters= 35
5x meters= 175
6x - 8 = 202
Step-by-step explanation:
x + 5x + (6x - 8)= 412
12x - 8= 412
12x = 412 + 8
12x = 420
x= 35
5x = 35× 5
= 175
6x - 8= 6(35) - 8
= 210 - 8
= 202
