Jan's age is 3 years less than twice tritt's age. the sum of their ages is 30. find their ages

Let Tritt's age = t & Jan's age = 2t - 3

if the sum of their ages equals 30 then..

combine terms and simplify

now simply divide

and to find Jan's age just plug 9 in



Jan's age = 15
Tritt's age = 9

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
