Solve 0.8*(y-1)+x=0.875+(x-1)

$$0.8 \times ( y - 1 ) + x = 0.875 + ( x - 1 )$$

Solve for y

$$y=0.84375$$

Steps for Solving Linear Equation

Use the distributive property to multiply 0.8 by y-1.

$$0.8y-0.8+x=0.875+x-1$$

Subtract 1 from 0.875 to get -0.125.

$$0.8y-0.8+x=-0.125+x$$

Add 0.8 to both sides.

$$0.8y+x=-0.125+x+0.8$$

Add -0.125 and 0.8 to get 0.675.

$$0.8y+x=0.675+x$$

Subtract x from both sides.

$$0.8y=0.675+x-x$$

Combine x and -x to get 0.

$$0.8y=0.675$$

Divide both sides by 0.8.

$$y=\frac{0.675}{0.8}$$

Expand \frac{0.675}{0.8} by multiplying both numerator and the denominator by 1000.

$$y=\frac{675}{800}$$

Reduce the fraction \frac{675}{800} to lowest terms by extracting and canceling out 25.

$$y=\frac{27}{32}$$

Solve for x (complex solution)

$$x\in \mathrm{C}$$

$$y = \frac{27}{32} = 0.84375$$

Solve for x

$$x\in \mathrm{R}$$

$$y = \frac{27}{32} = 0.84375$$
