steve is 6 years younger than twice Rebecca’s age. If the sum of Steve and Rebecca’s age is 30, how old is Steve and how old is Rebecca

Firstly , Let Rebecca age be R and Steve age be S

Steve is 6 years younger than twice Rebecca age

Since steve is younger, then we will be using subtraction as the order of operation

Since Rebecca age is twice

Then, R x 2

=2R

Steve is 6 years younger than twice of Rebecca age

Mathematically ,

 ---------------- equation 1

the sum of Steven and Rebecca age is 30

------------------ equation 2

Solve equation 1 and equation 2 simultaneously

Substitute into equation 2

Collect like terms

Divide both sides by R
