Answer:
The answer is 87/2 or 43.5
Step-by-step explanation:
x + (x + 2) + 6x + 10) = 360
x + x + 2 + 6x + 10 = 360
8x + 12 = 360
8x = 348
x = 43.5
Given
x + (x + 2) + (6x + 10) = 360 ← distribute parenthesis by 1
x + x + 2 + 6x + 10 = 360, that is
8x + 12 = 360 ( subtract 12 from both sides )
8x = 348 ( divide both sides by 8 )
