Christine's age is 6 more than ken's age. Three times ken's age plus 5 times Christina's age is equal to 46.how old is christine?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
C = K + 6, (1)
3K + 5C = 46. (2)
Substitute (1) into (2), simplify and solve.
3K + 5*(K+6) = 46,
3K + 5K + 30 = 46,
8K = 46 - 30 = 16,
K = 2, C = K + 6 = 2+6 = 8.
Answer. K =2, C = 8.
