To solve a problem like this, you can use a method called cross-multiplying. This is when you multiply the denominator of the first fraction by the numerator of the other and then multiply the two remaining numbers.
To make this easier on yourself, simplify first!
Multiply x by 2 and multiply 4 by 1.
2x = 4 Divide both sides by 2.
x = 2
You can check this by comparing the fractions with 2 in the place of x.
Simplify!
The fractions are equal, so
x = 2 .
