[tex]- \frac{2}{3} w + 5 = 4[/tex]
Refine:
[tex]5 - \frac{2w}{3} = 4[/tex]
Multiply both sides by 3 :
[tex]3 * 5 -3* \frac{2w}{3} = 3*4[/tex]
Refine:
[tex]15 - 2 w = 12[/tex]
Subtract 15 from both sides:
[tex]15 - 2w - 15 = 12 - 15[/tex]
[tex]- 2w = -3[/tex]
Divide both side by -2 :
[tex] \frac{-2w}{-2} = \frac{-3}{-2} [/tex]
[tex]w = \frac{3}{2} [/tex]
hope this helps!.
