Question

Use the diagram to Solve for x:

Answer 1

$\\ \bull\tt\longmapsto 2(31x+3)=192$

$\\ \bull\tt\longmapsto 31x+3=\dfrac{192}{2}$

$\\ \bull\tt\longmapsto 31x+3=96$

$\\ \bull\tt\longmapsto 31x=96-3$

$\\ \bull\tt\longmapsto 31x=93$

$\\ \bull\tt\longmapsto x=\dfrac{93}{31}$

$\\ \bull\tt\longmapsto x=3$
