Question

System A:x=3y=-9 2x=y=4 system B: 3x+4y=-9 2x+y=4 how can we get system b from system A? Are the systems Equivalent? TEST NEED HELP!! ASAP

Answer 1

To get System B from System A, we need to separate the equations in System A and rearrange them to match the equations in System B.

Step-by-step explanation:

To get System B from System A, we need to change the equations in System A so that they match the equations in System B. Let's take a step-by-step approach:

1. Start with the first equation in System A: x = 3y = -9.

This equation has two equal signs, which is not correct. We need to separate the equations.

2. Rewrite the first equation as x = -9 and the second equation as y = -3.

3. Now we can rearrange the equations to match the equations in System B.

Multiply the first equation by 3: 3x = -27, and multiply the second equation by 2: 2y = -6.

4. Finally, rearrange the equations to match System B: 3x + 4y = -27 + 4(-6) = -9, and 2x + y = -18 + (-3) = -21.

So, after making these changes, we can see that System A is now equivalent to System B.
