7-63.

For each equation below, solve for $x$ and check your answer.

1. $10(0.02x−0.01)=1$

Distribute and multiply by $10$.
$20x−10=100$

Add $10$ to both sides.
$20x=110$

Divide both sides by $20$.

$x=5.5$

1. $\frac{1}{3}x-6=8$

Multiply by a common denominator to remove fractions. Refer to part (a) for more help.

1. $\frac { x } { 3 } + 1 = \frac { x } { 4 } - 1$

Refer to part (b).

1. $0.9x−2.1+0.9=0.2(5−x)$

Refer to part (a).

$x=2$
