John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11

What is the x-intercept and y-intercept of the equation 2x+1. 2o

Using elimination, what is -4x+2y=-12 4x+8y=-24
