Solve 22=8^2/2+6^2/2-x

$$22= \frac{ { 8 }^{ 2 } }{ 2 } + \frac{ { 6 }^{ 2 } }{ 2 } -x$$

Solve for x

$$x=28$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 2.

$$44=8^{2}+6^{2}-2x$$

Calculate 8 to the power of 2 and get 64.

$$44=64+6^{2}-2x$$

Calculate 6 to the power of 2 and get 36.

$$44=64+36-2x$$

Add 64 and 36 to get 100.

$$44=100-2x$$

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

$$100-2x=44$$

Subtract 100 from both sides.

$$-2x=44-100$$

Subtract 100 from 44 to get -56.

$$-2x=-56$$

Divide both sides by -2.

$$x=\frac{-56}{-2}$$

Divide -56 by -2 to get 28.

$$x=28$$
