Question

1. show whether the values x = 5 and y = 6 make the equation 7x - 3y = 19 true.

Explanation:

Step1: Substitute x and y values

Substitute \( x = 5 \) and \( y = 6 \) into the left - hand side of the equation \( 7x-3y \).
The left - hand side of the equation is \( 7x - 3y \), so we have \( 7\times5-3\times6 \).

Step2: Calculate the left - hand side

First, calculate the multiplications: \( 7\times5 = 35 \) and \( 3\times6=18 \).
Then, calculate the subtraction: \( 35 - 18=17 \).

Step3: Compare with the right - hand side

The right - hand side of the equation \( 7x - 3y = 19 \) is 19.
Since \( 17
eq19 \), the left - hand side is not equal to the right - hand side when \( x = 5 \) and \( y = 6 \).

Answer:

The values \( x = 5 \) and \( y = 6 \) do not make the equation \( 7x-3y = 19 \) true.
