Answer:
Multiply 4x+3y=−1 by 3. Multiply 3x−5y=4 by −4 . Add the resulting equations together.
Step-by-step explanation:
Given the simultaneous equation below:
4x+3y=−1 ...(1) × 3
3x−5y=4 ...(2) × -4
Using elimination method to solve the problem,
Before we can eliminate x, the coefficient of x in both equation must have similar whole number as coefficient.
To make the coefficient equal, we will multiply equation 1 by 3 and equation 2 by -4 as shown above
The equations will then become
12x+9y = -3
-12x+20y = -16
Then we will add the resulting simultaneous equations.
The steps that would allow her to eliminate the x terms in the system of equations is to "Multiply 4x+3y=−1 by 3. Multiply 3x−5y=4 by −4 . Add the resulting equations together"
