Solve for b 1/4b-2=-1/2b+4

$\frac{1}{4} b - 2 = - \frac{1}{2} b + 4$

Step 1

Combine $\frac{1}{4}$ and $b$ .

$\frac{b}{4} - 2 = - \frac{1}{2} b + 4$

Step 2

Combine $b$ and $\frac{1}{2}$ .

$\frac{b}{4} - 2 = - \frac{b}{2} + 4$

Step 3

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

Add $\frac{b}{2}$ to both sides of the equation.

$\frac{b}{4} - 2 + \frac{b}{2} = 4$

To write $\frac{b}{2}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$\frac{b}{4} + \frac{b}{2} \cdot \frac{2}{2} - 2 = 4$

Write each expression with a common denominator of $4$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{b}{2}$ by $\frac{2}{2}$ .

$\frac{b}{4} + \frac{b \cdot 2}{2 \cdot 2} - 2 = 4$

Multiply $2$ by $2$ .

$\frac{b}{4} + \frac{b \cdot 2}{4} - 2 = 4$

Combine the numerators over the common denominator.

$\frac{b + b \cdot 2}{4} - 2 = 4$

Add $b$ and $b \cdot 2$ .

Reorder $b$ and $2$ .

$\frac{b + 2 \cdot b}{4} - 2 = 4$

Add $b$ and $2 \cdot b$ .

$\frac{3 b}{4} - 2 = 4$

Step 4

Move all terms not containing $b$ to the right side of the equation.

Add $2$ to both sides of the equation.

$\frac{3 b}{4} = 4 + 2$

Add $4$ and $2$ .

$\frac{3 b}{4} = 6$

Step 5

Multiply both sides of the equation by $\frac{4}{3}$ .

$\frac{4}{3} \cdot \frac{3 b}{4} = \frac{4}{3} \cdot 6$

Step 6

Simplify both sides of the equation.

Simplify the left side.

Simplify $\frac{4}{3} \cdot \frac{3 b}{4}$ .

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{4}{3} \cdot \frac{3 b}{4} = \frac{4}{3} \cdot 6$

Rewrite the expression.

$\frac{1}{3} (3 b) = \frac{4}{3} \cdot 6$

Cancel the common factor of $3$ .

Factor $3$ out of $3 b$ .

$\frac{1}{3} (3 (b)) = \frac{4}{3} \cdot 6$

Cancel the common factor.

$\frac{1}{3} (3 b) = \frac{4}{3} \cdot 6$

Rewrite the expression.

$b = \frac{4}{3} \cdot 6$

Simplify the right side.

Simplify $\frac{4}{3} \cdot 6$ .

Cancel the common factor of $3$ .

Factor $3$ out of $6$ .

$b = \frac{4}{3} \cdot (3 (2))$

Cancel the common factor.

$b = \frac{4}{3} \cdot (3 \cdot 2)$

Rewrite the expression.

$b = 4 \cdot 2$

Multiply $4$ by $2$ .

$b = 8$
