1-52.

Solve each of the following equations. Homework Help ✎

1. $3.9x−2.1=11.2x+51.7$

Isolate all x's on the same side.

$3.9x−2.1=11.2x+51.7$

$−7.3x−2.1=51.7$

Isolate all constants on the same side.

$−7.3x=53.8$

Divide by the coefficient of x.

$x\approx−7.37$

2. $\frac{1}{5}x−2=\frac{13}{25}-0.7x$

Notice that both fractions in this problem can be changed to exact decimal values.

$x=2.8$
