Answer:
The value of the first number, x, is equal to 18.
The value of the second number, y, is equal to 90.
The value of the third number, z, is equal to 77.
Step-by-step explanation:
x + y + z = 185
y = 5x
z = y - 13
Because we already have a value for y, we already have a value for z. We can now solve for a value of x.
x + 5x + 5x - 13 = 185
Add 13 to both sides.
x + 5x + 5x = 198
Combine like terms.
11x = 198
Divide both sides by 11.
x = 18
Because we have a value of x, we can solve for the exact values of y and z.
y = 5(18)
y = 90
z = (90) - 13
z = 77
Hope This Helps!
