Question

solve the system of linear equations by substitution.
x = 8
y = 3x - 11
what is the value of y?

Explanation:

Step1: Identify substitution value

We know \( x = 8 \) from the first equation.

Step2: Substitute x into y's equation

Substitute \( x = 8 \) into \( y = 3x - 11 \). So \( y = 3\times8 - 11 \).

Step3: Calculate the value of y

First, calculate \( 3\times8 = 24 \). Then, \( 24 - 11 = 13 \).

Answer:

The value of \( y \) is \( 13 \).
