Suppose Yolanda has $Y$ dollars, Brian has $B$ dollars, and Charlie has $C$ dollars. Now put the fact you know into equation form.
Equation 1 has three variables, $Y, B$ and $C$ and I would like to transform it into an equation with one variable. Equation 2 says $B = Y  2$ or $Y = B + 2$ and hence if I substitute $Y = B + 2$ into equation 1 I will have converted equation 1 to an equation with two variables. $B$ and $C$. Equation 3 says $C = 3 \times B$ and now if I substitute $C = 3 \times B$ into the converted equation 1 I will have an equation with only one variable, $B.$ Solve this equation for $B.$ Penny
