When we add the two equations vertically. we get 5x=10 (3x+2x and 4+6, the y's cancel each other out) ∴x=2. Substitute this into any of the equations and we get y=2

so, x=2 and y=2

81 = k *27

Divide each side by 27

81/27 = 27k/27

3=k

The constant of variation is 3

Hullan's age is three times Thomas's age. The sum of their ages is 92. What is Thomas's age?

Ksju [112]

Answer: 23

Step-by-step explanation: You can start by setting this up as an equation like so,

X + 3(X) =92 where x is Thomas’ age and the 3x indicates Hullans age being 3 times greater than Thomas.

Combine the x’s

4(x) = 92

Divide by 4 X = 92/4

92/4 = 23, x = 23
