3q +2z3q+2z

Explanation:

An expression is a maths sentence or maths statement.
There are two numbers mentioned, q and qandz

'Tripled' means multiplied by 33, so qq tripled is 3q3q

'Doubled' means multiplied by 22, so zz doubled is 2z2z

The required expression is a statement that these two terms are added together:

3q +2z3q+2z

Notice that we are not told what the answer must be equal to, so we cannot write an equation.
