Question 372846
to eliminate a variable , the variable has to have the same (or opposite) coefficient in two equations
so that when the equations are subtracted (or added) the variable is canceled out


multiplying the 1st eqn by 4 ___ 28x - 24y = -354
adding this to the 2nd eqn will ELIMINATE the x variable


find the value of y , then substitute back to find the value of x



OOPS...good thing to notice ___ multiplying the 1st eqn by 4 GIVES the 2nd eqn
this means the equations are the same , so there is no unique solution (infinite number)
