Question

Julio wants to solve the system shown using the elimination method. Which is the best way to begin?

Answer 1

Answer:

B. Multiply each term in x - 12y = 2 by 4 and add it to the other original equation.

Step-by-step explanation:

The expression are two linear equation and can be solved simultaneously

$x - 12y = 2------------------1$

$-4x + 7y = 12----------------------2$

1. we need to multiply each term in eqn 1 by 4 and add it to the other

original equation(2).

$4x - 48y = 8----------------3\\-4x + 7y = 12---------------2$

Adding both 3 and 2 we have

$4x - 48y = 8----------------3\\-4x + 7y = 12---------------2$

2. once we have gotten the value of y

we then substitute it in any of the equations to solve for x
