Solve 21/6*3=-y

$$2 \frac { 1 } { 6 } \times 3 = - y$$

Solve for y

$$y = -\frac{13}{2} = -6\frac{1}{2} = -6.5$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 6.

$$\left(2\times 6+1\right)\times 3=-6y$$

Multiply 2 and 6 to get 12.

$$\left(12+1\right)\times 3=-6y$$

Add 12 and 1 to get 13.

$$13\times 3=-6y$$

Multiply 13 and 3 to get 39.

$$39=-6y$$

Swap sides so that all variable terms are on the left hand side.

$$-6y=39$$

Divide both sides by -6.

$$y=\frac{39}{-6}$$

Reduce the fraction \frac{39}{-6} to lowest terms by extracting and canceling out 3.

$$y=-\frac{13}{2}$$
