Question

solve each equation. check your solution. (examples 1–4)

1. $5x + 2 = 17$
2. $19 = 4x + 3$
3. $-18 = 6 + 6x$
4. $-3x - 9 = -15$
5. $-6x - 7 = 17$
6. $-5 = 3x - 14$
7. $3.8 = 2x - 11.2$
8. $5x - 3.3 = 7.2$
9. $1.3x + 1.5 = 5.4$
10. $2 + \frac{1}{6}x = -4$
11. $-\frac{1}{2}x - 7 = 18$
12. $-9 = \frac{2}{7}x + 5$

test practice

1. open response the table shows the costs of a membership and fruit baskets at a discount warehouse club. mrs. williams paid a total of $105 for her annual membership fee and several fruit baskets as gifts for her coworkers. solve the equation $15x + 30 = 105$ to find the number of fruit baskets mrs. williams purchased.

item	cost ($)
fruit basket	15

Explanation:

Step1: Subtract 30 from both sides

$15x + 30 - 30 = 105 - 30$
$15x = 75$

Step2: Divide both sides by 15

$\frac{15x}{15} = \frac{75}{15}$
$x = 5$
