First: solve for "m" and keep it on one side by itself > subtract 18 from both sides - opposite side means opposite sign.
18 - 18 + m = - 57 - 18
m = -75

Multiply the 2nd equation by using 3 to get rid of the x's 6x + 18y = fifty seven 6x - 9y = - 24 Take the 2nd from the 1st equation 27y = eighty one y = 3. replace for y in the two equation 6x + fifty 4 = fifty seven 6x = fifty seven -fifty 4 6x = 3 x = 3/6 or a million/2 examine a million - 9 = - 8 answer is actual
