An equation in the form ax + b = 0, a 0, such as 3x + 17 = 0, is called a/an (1) equation in one variable.

(1)

linear

simple equivalent inconsistent

2.Select the answer that best completes the given statement.

The addition property of equality states that if a = b, then a + c = (1)

(1)b.

b c. c.

b + c.

b + ac.

3.Select the answer that best completes the given statement.

The first step in solving 4 + 2(x 8) = 3x + 11 is to (1)

(1)

subtract 11 from both sides. subtract 4 from both sides. apply the distributive property. subtract 3x from both sides.

4.Select the answers that best complete the given statements.

In solving an equation, if you eliminate the variable and obtain a false statement such as 2 = 3, the equation is a/an
