What is X plus 7y equals 33 and 3x 2y equals 7?
x + 7y = 33 (Eqn 1) 3x + 2y = 7 (Eqn 2) Multiply Eqn 1 by 3, now the equations are 3x + 21y = 99 (Eqn 3) 3x + 2y = 7 (Eqn 2) Subtract Eqn 2 from Eqn 4 and the result of subtraction is 19y = 92 Hence y = 92/19 Now substitute the value of y in Eqn 1 x + (7) x (92/19) = 33 x = 33 - 644/19 = -(17/19)
What are the solutions to the simultaneous equations of 6.6x plus 16.5y equals 52.8 and -16.5x -6.6y equals 6.6 showing key stages of work?
Eqn (A): => 2x + 5y = 16 Eqn (B): => 5x + 2y = -2 5*Eqn (A) - 2*Eqn (B): 21y = 84 => y = 4 Substituting for y in Eqn (a): x = -2
X - 2y equals 3 and 5x plus 3y equals 2 where do they intersect?
Eqn 1: x - 2y = 3 Eqn 2: 5x + 3y = 2 5 times Eqn 1: 5x - 10y = 15 Eqn 2 - 5*Eqn 1: 0x + 13y = -13 so that 13y = -13 or y = -1 Substitute in Eqn 1: x + 2*1 = 3 x + 2 = 3 x = 1 Solution: x = 1, y = -1
What would the solution be if c-5d equals 2 and 2c plus d equals 4?
c - 5d = 2 2c + d = 4 Multiply eqn 1 by 2: 2c - 10d = 4 Subtract this from eqn 2: 0c + 11d = 0 which implies that d = 0 Then, by eqn 1, c = 2

How do you find the radius of a circle if you know three points on the circumference?
First lets look at the equation for a circle... (x - h)2 + (y - k)2 = r2 What do I know? The center must be constant so H and K are two variables I need to solve for... and I know I need to solve for R as well! take your points (i'm making a simple circle with center (0,0) with radius of 1...) 1,0 0,1 -1,0 I have my 3 points.... I will make myself 3 equations: eqn #1a: (1 - h)2 +(0 - k)2 = r2 eqn #2a: (0 - h)2 +(1 - k)2 = r2 eqn #3a: (-1 - h)2 +(0 - k)2 = r2 Ok so now I have some equations to play with... eqn #1b: h2 - 2h +1 + k2 = r2 eqn #2b: h2 + k2-2k +1 = r2 eqn #3b: h2 + 2h +1 + k2= r2 The rest is subsitution... We want r's value so lets see. Lets take eqn #1b and #2b... h2 - 2h +1 + k2 = h2 + k2-2k +1 Balance it out cancle and such try to make it = 0 - 2h = -2k h = k so now I know I can replace h with k or k with h It doesn't matter which one I make to the other if we had 2h = k I would put 2h in its just simpler... keep in mind either way works. eqn #1c: k2 - 2k +1 + k2 = r2 eqn #2c: k2 + k2-2k +1 = r2 eqn #3c: k2 + 2k +1 + k2= r2 collect terms eqn #1c: 2k2 - 2k +1 = r2 eqn 1 is the same as eqn 2! eqn #2c: 2k2 - 2k +1 = r2 eqn #3c: 2k2 + 2k +1= r2 We really have two equations left now it doesn't always work out this way. Set eqn 2 and 3 equal to each other via the r 2k2 - 2k +1 = 2k2 + 2k +1 do some cancling -2k = 2k at this point I know k = 0 its the only viable answer.... take any one of our origonal equations.... h2 - 2h +1 + k2 = r2 all the parts with k or h = 0; remember h = k = 0 1 = r2 1 = r If I had time I would do a more complex equation for yea... but this kinda gets the point across...

What is the x and y equal to if the problems are 6x-5y equals 11 and -4x plus 7y equals 11?
6x - 5y = 11 --------- Eqn 1 -4x + 7y = 11 ------- Eqn 2 ___________ 24x - 20y = 44 ------ Eqn 1 multiplied by 4 on both sides, equation won't change -24x + 42y = 66 ---- Eqn 2 multiplied by 6 on both sides, equation won't change _____________ 0x + 22y = 110 ----- Adding the two eqns above gives you this result _____________ That is 22y = 110, or y = 5 (Answer) Now substitute the value of y in either eqn 1 or eqn 2 (we will use eqn 1) 6x - 5(5) = 11 6x = 11 + 25 = 36 x = 6 (Answer)

What two numbers have a difference of 7 and a sum of 29?
X - Y = 7 eqn 1X + Y = 29 eqn 2Taking eqn 1 we can isolate for XX-Y = 7add Y to both sidesX = 7 + YSubstituting this into eqn 2 we getX + Y = 29(7 + Y) + Y = 297+ 2Y = 29subtract 7 from both sides2Y = 22divide both sides by 2Y = 11Substituting this into eqn 1 we getX - 11 = 7add 11 to both sidesX = 18So X = 18 and Y = 11
Why is the concept of self GMD is not applicable for capacitance?
The radius in the eqn. of capacitance is actual outside radius of the conductor whereas for inductance eqn. The radius is the self GMD of the conductor.
