The value of x in the equation is -18

How to solve the equation?

The equation is given as:

[tex]-\frac 23x - \frac{21}4 = \frac{27}4[/tex]

Add 21/4 to both sides of the equation

[tex]-\frac 23x = 12[/tex]

Multiply both sides by -3/2

[tex]x = -18[/tex]

Hence, the value of x in the equation is -18
