Question

Solve ⇒ \frac{3}{7}(7x-1)-(2x-1-\frac{x}{2})=x+\frac{3}{2}

\rule{300}{1}

Answer

Let's solve your equation step-by-step.

\frac{3}{7}(7x-1)-(2x-1-\frac{x}{2})=x+\frac{3}{2}

Step 1: Simplify both sides of the equation.

\frac{3}{7}(7x-1)-(2x-1-\frac{x}{2})=x+\frac{3}{2}

(Distribute the Negative Sign)

\frac{3}{7}(7x-1)+-1(2x-1-\frac{x}{2})=x+\frac{3}{2}

\frac{3}{7}(7x-1)+-1(2x)+(-1)(-1)+-1(\frac{-1}{2} x)=x+\frac{3}{2}

\frac{3}{7} (7x-1)+-2x+1+\frac{1}{2}x =x+\frac{3}{2}

(Distribute)

(\frac{3}{7})(7x)+(\frac{3}{7})(-1)+-2x+1+\frac{1}{2}x=x+\frac{3}{2}

3x+\frac{-3}{7}+-2x+1+\frac{1}{2}x = x+  \frac{3}{2}

(Combine Like Terms)

(3x+-2x+\frac{1}{2}x )+(\frac{-3}{7} +1)=x+\frac{3}{2}

\frac{3}{2}x+\frac{4}{7}=x+\frac{3}{2}

Step 2: Subtract x from both sides.

\frac{3}{2}x+\frac{4}{7}-x=x+\frac{3}{2}-x

\frac{1}{2}x+\frac{4}{7}=\frac{3}{2}

Step 3: Subtract \frac{4}{7} from both sides.

\frac{1}{2}x+\frac{4}{7}-\frac{4}{7} =\frac{3}{2}-\frac{4}{7}

\frac{1}{2}x=\frac{13}{14}

Step 4: Multiply both sides by 2.

2\times \frac{1}{2}x=2\times \frac{13}{14}

x=\frac{13}{7}

\bf \therefore x=\frac{13}{7} \ in \ the \ equation =>\  \frac{3}{7}(7x-1)-(2x-1-\frac{x}{2})=x+\frac{3}{2}

\rule{300}{1}
