[tex] -\dfrac{4}{3} y + (- 2) = 15[/tex]
Evaluate the + ( -) to give - :
[tex] -\dfrac{4}{3} y - 2 = 15[/tex]
Add 2 on both sides:
[tex] -\dfrac{4}{3} y= 15 + 2[/tex]
Evaluate the Right Hand Side:
[tex] -\dfrac{4}{3} y= 17[/tex]
DIvide by -3 on both sides:
[tex]4 y= 17 \times (-3)[/tex]
Evaluate the Right Hand Side:
[tex]4 y= -51[/tex]
Divide by 4 on both sides:
[tex]y = -\dfrac{51}{4} [/tex]
Simplify to mixed fraction:
[tex]y = -12\dfrac{3}{4} [/tex]
