Can you please show all the work on paper

A system of equations is shown below.
Equation A: 5x + 9y = 12
Equation B: 4x – 3y = 8
Which method eliminates one of the variables?
1
1.
Multiply equation A by - 3 and add the result to equation B.
2.
Multiply equation B by 3 and add the result to equation A.
Multiply equation A by 2 and equation B by -6 and add the results
3.
together.
Multiply equation B by 5 and equation A by 4 and add the results
4.
together.

Expert Solution

Step 1

Given equation :

A: 5x+9y=12

B: 4x-3y=8

We have to eliminate variable either x or y. To eliminate the variable equal the coefficient of variable(either x or y). for this we multiply by some number to equate the coefficient then add or subtract both equations.
