​

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

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29

60 2(x + 2) in the diagram, gef and hef are congruent. what is the value of x?
