What is the answer to the equation -4x plus 3y plus 3z equals -209 -6x - y - 8z equals -209 -9x plus 4y - 7z equals -418?
-4x + 3y + 3z = -209-6x - y - 8z = -209-9x + 4y - 7z = -418Make a simple equation from elimination.-4x + 3y + 3z = -6x- y - 8z2x + 4y + 11z = 0-4x + 3y + 3z = -2094x + 8y + 22z = 011y + 25z = -209Make another simple equation.-36x - 6y - 48z = -1254-36x + 16y - 28z = -1672-22y - 20z = 418Solve for "z" with the 2 simple equations and then subsitute in simple equations for the solution of "y".22y + 50z = -418-22y - 20z = 41830z = 0z = 011y + 25(0) = -209y = -19Subsitute "y" and "z" and solve for "x".-6x + 19 = -209-6x = -228x = 38(38, -19, 0).
What is true 15 plus 0 equals 0 15-0 equals 0 15 percent 0 equals 0 0 percent 15 equals 0?
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
The sum of two numbers is 22 and their product is 117 find the number?
Two equations are needed to solve for two variables, and we have them. Let one number=x and the other=y x+y=22 and x*y=117 subtract y from both sides and you get x=22-y substituting (22-y) in for x gives (22-y)*y=117 after you distribute the y, 22y-y2=117 the easiest step would be to add y2 to both sides and subtract 22y from both sides 22y=117+y2 0=y2-22y+117 factor to (y-13)(y-9)=0 so y=13 or 9 One of the numbers is 13 and the other is 9
