 Can one equation with two variables be solved algebraically? 2019-08-30 From Don:Can one equation with two variables be solved algebraically?Answered by Penny Nom. An impossible problem 2017-09-15 From Fay:Given math homework problem of: Gary and Larry given 2 numbers and told to add together. Gary subtracted and got 14. Larry multiplied and got 799. I tried substitution: X-Y=14 and X x Y=799 X= Y+14 (Y+14) Y=799 and here I'm stuck at Y squared+14 Y= 799 using substitution I got 47x17=799 but not 14b when subtracted. HELP?????Answered by Penny Nom. Linear equations in two variables 2015-12-13 From priya:I have problem in solving these equations please help me today itself very urgent: I)2x+y=y II)pie*x+y=9Answered by Penny Nom. An equation in two variables 2013-05-14 From Steve:Verify solutions to an equation in two variables. 4x-2y=8 (3, 2)Answered by Penny Nom. Coefficient of variation 2011-04-14 From Braden:When determining coefficient of variation (CV) or %CV is it possible to calculate %CV for two variables? For instance can %CV be used to determine the precision of 5 data points on a graph using the X and Y coordinates? or does %CV need to be determined for each variable separately?Answered by Robert Dawson. Solve for y in terms of x 2008-08-10 From Rosie:Solve equation for y -4x=12+3yAnswered by Penny Nom. g(m-1,2n)+n 2008-06-07 From Florence:What does g(m-1,2n)+n for m>0, n>=0 mean.Answered by Penny Nom. Solve for a and t 2004-10-23 From Justin:How do I solve for "a" and "t" in the equations: 1000t= -4000 + 2000t + (1/2)at^2 1000=2000 + atAnswered by Penny Nom. Factor completely 2002-03-07 From Taylor:I'm supposed to completely factor this but I don't know what to do with all the variables. a3b5 - a2b5 - 12ab5. Does it have anything to do with b5 being a common factor or am I completely off? Answered by Penny Nom. Solve for two variables 2001-02-25 From A student:How do I solve for %1 and %2 in the following formula when T1, T2 and T3 are known? %1 and %2 are ratios of the same element, therefore %1 + %2 = 100% (%1 x T1) + (%2 x T2) = T3Answered by Penny Nom.
