Solve 105-15y+4y/2=21

$$\frac { 105 - 15 y + 4 y } { 2 } = 21$$

Solve for y

$$y = \frac{63}{11} = 5\frac{8}{11} \approx 5.727272727$$

Steps for Solving Linear Equation

Multiply both sides by 2.

$$105-15y+4y=21\times 2$$

Combine -15y and 4y to get -11y.

$$105-11y=21\times 2$$

Multiply 21 and 2 to get 42.

$$105-11y=42$$

Subtract 105 from both sides.

$$-11y=42-105$$

Subtract 105 from 42 to get -63.

$$-11y=-63$$

Divide both sides by -11.

$$y=\frac{-63}{-11}$$

Fraction \frac{-63}{-11} can be simplified to \frac{63}{11} by removing the negative sign from both the numerator and the denominator.

$$y=\frac{63}{11}$$
