Which one of these strategies would eliminate a variable in the system of equations 8x+5y=-7, -7x+6y=-4

For this case we have the following system of equations:

If we want to solve the system by the "elimination" method, we must multiply some (or two) of the equations by a number such that when one is added, one of the variables is eliminated.

Multiplying by 6 the first equation we have:

Multiplying by -5 second equation we have:

If we add both equations, the variable y is eliminated.

We can also multiply the first equation by 7:

We multiply the second equation by 8:

Adding the equations eliminates the variable x.

One strategy may be to multiply the first equation by 7, the second equation by 8 and add.

the infinity sign
