$x=\displaystyle \frac{7.27}{455}\approx 1.60$

Work Step by Step

$\displaystyle \frac{0.26x-1.94}{303-2.44x}=1.76$ We cross multiply: $0.26x-1.94=1.76(3.03-2.44x)$ And distribute: $0.26x-1.94=5.33-4.29x$ And combine $x$ terms: $4.55x=7.27$ And solve for $x$: $x=\displaystyle \frac{7.27}{455}\approx 1.60$
