$x = 50$ $x=50$

$0.20 x + 0.25 (70) = 27.5$ $0.20x+0.25(70)=27.5$

Combine like terms
$0.2 x + 17.5 = 27.5$ $0.2x+17.5=27.5$

Subtract $17.5$ $17.5$ from both sides
$0.2 x = 10$ $0.2x=10$

Convert decimal to fraction (if you want)
$\frac{2}{10} x = 10$ $2/10x=10$

Multiply both sides by $10$ $10$
$2 x = 100$ $2x=100$

Divide both sides by $2$ $2$
$x = 50$ $x=50$
