You need to solve a system of equations. You decide to use the elimination method. Which of these is not allowed?

2x – 3y = 12 Equation 1

–2x + y = 8 Equation 2

AAdd equation 2 to equation 1.
BMultiply equation 2 by 3. Then subtract the result from equation 1.
CAdd the left side of equation 2 to the left side of equation 1.

Verified Answer :

Answer:

The correct option is C

Step-by-step explanation:

Given two equations

2x – 3y = 12 →   Equation 1

–2x + y = 8 →   Equation 2

we need to solve a system of equations to use the elimination method then which option is not allowed.

As in the elimination method we have to eliminate one of the variable by making the coefficients of x and y equal. From all the three options only the option C in which the addition is only done in the left side of both equations which is not possible.

Hence, option C is not allowed.
