We have the following:

Describe/Draw

The statement tells us that the number of girls was 6 plus twice the number of boys and that in total there are 156 students.

Define

Number of girls: y, y = 6 + 2x

Number of boys: x

Number of students: 154

Do

`\begin{gathered} x+y=156 \\ x+6+2x=156 \\ 3x=156-6 \\ x=(150)/(3) \\ x=50 \end{gathered}`

for y:

`y=6+2\cdot50=6+100=106`

Decide

The answer is correct because the sum of both is equal to 156 students

Declare

In total there are 50 boys and 106 girls
