Question

1. $4c - 3$

$c = -2$

1. $\frac{1}{3}x + 5$

$x = -6$

Explanation:

Problem 4:

Step1: Substitute \( c = -2 \) into \( 4c - 3 \)

\( 4\times(-2) - 3 \)

Step2: Calculate multiplication first

\( -8 - 3 \)

Step3: Calculate subtraction

\( -11 \)

Step1: Substitute \( x = -6 \) into \( \frac{1}{3}x + 5 \)

\( \frac{1}{3}\times(-6) + 5 \)

Step2: Calculate multiplication

\( -2 + 5 \)

Step3: Calculate addition

\( 3 \)

Answer:

\( -11 \)
