MACHO ATE 125 HOT DOGS OVER A FIVE DAY PERIOD. EACH DAY HE AT SEVEN MORE HOT DOGS THAN ON THE PREVIOUS DAY. HOW MANY HOT DOGS DID HE EAT ON THE FIRST DAY?

• MATH - ,

first day --> x
2nd day --> x+7
etc

x + x+7 + x+14 + x+21 + x+28 = 125
5x = 55
x = 11

• MATH - ,

x = (x+7) + (x+14) + (x+21) + (x+28) =
125,
5x + 70 = 125,
5x = 125 - 70 = 55,
x = 11.

I agree 100% with that answer and I understand all of it besides:
5x + 70 = 125

• MATH - ,

X + (X + 7) + (X + 14) + (X + 21) + (X + 28) = 125.

X + X + X + X + X = 5X.

7 + 14 + 21 + 28 = 70.
5X + 70 = 125
5X = 125 - 70 = 55
X = 11.

• MATH - ,
