#### Answer

$x=45.5$

#### Work Step by Step

We are trying to solve for the given variable so that the proportion is true.
To determine if a proportion is true, we have to find if the cross products are equal.
The cross products of $\frac{a}{b}=\frac{c}{d}$ are $a \cdot d$ and $b \cdot c$.
$26*49=28*x$
$1274=28x$
$1274\div28=28x\div28$
$x=45.5$
