Basic Math Examples

$t = 2 r + 2 t$

Step 1

Move all terms containing $t$ to the left side of the equation.

Step 1.1

Subtract $2 t$ from both sides of the equation.

$t - 2 t = 2 r$

Step 1.2

Subtract $2 t$ from $t$ .

$- t = 2 r$

Step 2

Divide each term in $- t = 2 r$ by $- 1$ and simplify.

Step 2.1

Divide each term in $- t = 2 r$ by $- 1$ .

$\frac{- t}{- 1} = \frac{2 r}{- 1}$

Step 2.2

Simplify the left side.

Step 2.2.1

Dividing two negative values results in a positive value.

$\frac{t}{1} = \frac{2 r}{- 1}$

Step 2.2.2

Divide $t$ by $1$ .

$t = \frac{2 r}{- 1}$

Step 2.3

Simplify the right side.

Step 2.3.1

Move the negative one from the denominator of $\frac{2 r}{- 1}$ .

$t = - 1 \cdot (2 r)$

Step 2.3.2

Rewrite $- 1 \cdot (2 r)$ as $- (2 r)$ .

$t = - (2 r)$

Step 2.3.3

Multiply $2$ by $- 1$ .

$t = - 2 r$
