What are the solutions to the simultaneous equation of 3x plus 2y equals 5x plus 2y equals 14 showing work?
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
How do you solve the equation 10x-2x-527?
10x-2x =8x-527
Equation 2x plus 5 equals 25 for x?
2x + 5 = 25 2x = 20x = 10
Simultaneous equation 2x-2y equals 10?
Simultaneous suggests at least two equations.
What is the simultaneous equation for 2x plus 5y equals 20?
Another straight line equation is needed such that both simultaneous equations will intersect at one point.
What is 2x plus y equals 1 2x equals minus y equals -5?
It seems to be some kind of simultaneous equation with too many equality signs in it.
Work out 2x equals y plus 7 and x-2 equals y simultaneous equation?
2x = y + 7 x - 2 = y substitute the y from the second equation into the first: 2x = x - 2 + 7 2x = x+5 x = 5 --> y = 5 - 2 y = 3
What is 2x-13 equals 5 This is an equation please help?
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
What is 5x plus 2y equals -18 2x-3y equals -11?
It's a simultaneous equation and can be solved by elimination which works out as:- x = -4 and y = 1
What is 2x plus 3y equals 17 and 3x minus 2y equals 0.5?
It is a simultaneous equation and when solved its solutions are x = 71/26 and y = 50/13
How do you solve -2x plus y equals -3 and -x plus 2y equals 3?
Simultaneous equations -2x + y = -3 -x + 2y = 3 Multiply the bottom equation by '-2' Hence -2x + y = -3 2x - 4y = -6 Add the two equations -3y = -9 Divide both sides by '-3' y = (+)3 Substitute in to either equ'n for 'x' -2x + 3 = -3 Subtract '3' from both sides -2x = -6 Divide both sides by '-2' x = (+)3 Hence (x,y) = ( 3,3)
Simultaneous equations cannot be solved?
Simultaneous Equations are very helpful because it can help u solve problems in real life. There are 2 ways to approach a simultaneous equation, Substitution and elimination method. As a good practice it is always good to practice your substitution method first. I wont go too advance for now but consider this question;Find two numbers whose sum is 21 and difference is 9.This question requires 2 equation to solve; thus it is call simultaneous equation.Solve: Let x be a number, and Let y be another number.x + y = 21 equation 1x - y = 9 equation 2Rearrange equation 2 to make equation 3(Equation 3 is just to sub into the other eqs)x = 9 + y equation 3Sub equation 3 into 1(9 + y) + y = 219 + 2y = 212y = 12y = 6 First solution!Sub y = 6 into equation 2x - 6 = 9x = 15 Second Solution!Therefore, the numbers are 15 and 6.In a simultaneous equation (with 2 variable) there will always be 2 answers.This is copied from my other worked examples. I do not really understand your question. If you have a simultaneous equation that you can't solve. Post it up and i will help.* * * * *Good answer, but spoiled by the last-but-one paragraph. Simultaneous linear equations with two variables can have no solutions (if the corresponding graphs are distinct parallel lines) or infinitely many solutions (if they are, in effect, the same line). And then, there are always simultaneous non-linear equations. Two quadratics, for example, can have 0, 1, 2 or infinitely many solutions.
