Solve y=800+0.25y+2.1*y

$$y = 800+0.25y+2.1 \times y$$

Solve for y

$$y = -\frac{16000}{27} = -592\frac{16}{27} \approx -592.592592593$$

Steps for Solving Linear Equation

Combine 0.25y and 2.1y to get 2.35y.

$$y=800+2.35y$$

Subtract 2.35y from both sides.

$$y-2.35y=800$$

Combine y and -2.35y to get -1.35y.

$$-1.35y=800$$

Divide both sides by -1.35.

$$y=\frac{800}{-1.35}$$

Expand \frac{800}{-1.35} by multiplying both numerator and the denominator by 100.

$$y=\frac{80000}{-135}$$

Reduce the fraction \frac{80000}{-135} to lowest terms by extracting and canceling out 5.

$$y=-\frac{16000}{27}$$
