Solve y=8.1109+(45-1)(7.7217-81109)/(5-4)

$$y = 8.1109 + \frac { ( 45 - 1 ) ( 7.7217 - 81109 ) } { ( 5 - 4 ) }$$

Solve for y

$$y=-3568448.1343$$

Steps for Solving Linear Equation

Subtract 1 from 45 to get 44.

$$y=8.1109+\frac{44\left(7.7217-81109\right)}{5-4}$$

Subtract 81109 from 7.7217 to get -81101.2783.

$$y=8.1109+\frac{44\left(-81101.2783\right)}{5-4}$$

Multiply 44 and -81101.2783 to get -3568456.2452.

$$y=8.1109+\frac{-3568456.2452}{5-4}$$

Subtract 4 from 5 to get 1.

$$y=8.1109+\frac{-3568456.2452}{1}$$

Anything divided by one gives itself.

$$y=8.1109-3568456.2452$$

Subtract 3568456.2452 from 8.1109 to get -3568448.1343.

$$y=-3568448.1343$$

Assign y

$$y≔-3568448.1343$$
