Question

1. carlos says the answer to the equation -9 =

a) carlos is wrong because you can’t s
b) carlos is wrong because -9 - 3 =
c) carlos is right because -9 - 3 = -
d) carlos is right because -9 + 3 = -

1. solve the equation 11x - 15 = 5x - 3

a) x = 2
b) x = 6
c) x = -3
d) x = \frac{3}{4}

1. solve the equation 3(w - 2) + 4 = -14

a) w = -19
b) w = 4
c) w = -4
d) w = -\frac{16}{3}

Explanation:

Question 6

Step1: Subtract \(5x\) from both sides

\(11x - 15 - 5x = 5x - 3 - 5x\)
\(6x - 15 = -3\)

Step2: Add 15 to both sides

\(6x - 15 + 15 = -3 + 15\)
\(6x = 12\)

Step3: Divide by 6

\(\frac{6x}{6} = \frac{12}{6}\)
\(x = 2\)

Step1: Distribute the 3

\(3w - 6 + 4 = -14\)
\(3w - 2 = -14\)

Step2: Add 2 to both sides

\(3w - 2 + 2 = -14 + 2\)
\(3w = -12\)

Step3: Divide by 3

\(\frac{3w}{3} = \frac{-12}{3}\)
\(w = -4\)

Answer:

A) \(x = 2\)
