What is a 2 step equation that equals 21?

Well, darling, a 2-step equation that equals 21 could be something like 2x + 5 = 21. First, you'd subtract 5 from both sides to get 2x = 16, then divide by 2 to find x = 8. Voila, you've got yourself a sassy solution!


What two step equation equals 29?

One out of many examples of two step equations that equal 29 is: (9 x 3) + 2


How do you find the solutions of the simultaneous equations of 2x plus 5y equals 16 and -5x-2y equals 2 showing work in step by step stages?

1 If: 2x+5y = 16 and -5x-2y = 2 2 Then: 2*(2x+5y =16) and 5*(-5x-2y = 2) is equvalent to the above equations 3 Thus: 4x+10y = 32 and -25x-10y = 10 4 Adding both equations: -21x = 42 or x = -2 5 Solutions by substitution: x = -2 and y = 4
