Answer:
x = 76
One-step equation: 8 = x - 68
Step-by-step explanation:
If we call the number of people that ate lasagna 'y', we can write the following equation:
y = (1/4)*x - 17
Nowing that the number of people that ate lasagna is two, we have that y=2, so we can find the value of x:
2 = (1/4)*x - 17
x/4 = 19
x = 76 people
From the first equation (y = (1/4)*x - 17) we can write an one-step equation:
y = (1/4)*x - 17 -> 4*y = x - 68
To solve this equation after using the value of y, we just need to sum 68 in both sides:
x - 68 = 8
x = 76
