Question

Which statement correctly explains how Andre could find the solution to the following system of linear equations using elimination?
8s-9t=15
7s-2t=12

Multiply the first equation by –7 and the second equation by 8, and then subtract.
Multiply the first equation by -7 and the second equation by 8, and then add.
Multiply the first equation by 2 and the second equation by 9, and then add.
Multiply the first equation by –2 and the second equation by 9, and then subtract.

Answer 1

Multiply the first equation by -7 and the second equation by 8, and then add. Then the correct option is B.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The system of the linear equations are given below.

8s – 9t = 15 …1

7s – 2t = 12 …2

Multiply the first equation by -7 and the second equation by 8, and then add.

–56s + 63t = -105

  56s – 16t = 96  

             47t = -9

Then the correct option is B.
