For the equation $\frac { 3 } { 200 }$ $+$ $\frac { x } { 50 }$ $=$ $\frac { 7 } { 100 }$: Homework Help ✎

1. Find a simpler equivalent equation (i.e., an equivalent equation with no fractions) and solve for $x$.

Multiply the equation by a common multiple of the denominators to remove the fractions.

$200\left(\frac{3}{200}+\frac{x}{50}=\frac{7}{100}\right)$

$3+4x=14$

Solve for $x$.
