Answer:

x = 1 $\frac{1}{4}$

Step-by-step explanation:

Expressing the diagram as an equation , that is

6x - 3 = 4 $\frac{1}{2}$ = $\frac{9}{2}$ ( multiply through by 2 to clear the fraction )

12x - 6 = 9 ( add 6 to both sides )

12x = 15 ( divide both sides by 12 )

x = $\frac{15}{12}$ = $\frac{5}{4}$ = 1 $\frac{1}{4}$
