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

equation one: 2x - 3y = 12
equation two: -x + 2y = 13

a. multiply equation 1 by 2 and equation two by 3. then add the new equations.

b. multiply the left side of equation 2 by 2. then subtract the result from equation 1.

c. multiply equation 2 by -2. then add the result to equation 1.

B

Step-by-step explanation:

The Elimination Method is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.

When multoplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).

So, option B is not allowed (it is not allowed to multiply only one part of equation)

is it i think

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
