5x+3=8 is a simple equation, and I can tell you off the top of my head the answer is 1. Here's how to work it: 5x+3=8 5x+3(-3)=8(-3) 5x=5 5x(/5)=5(/5) x=1
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. There is no equality symbol in the equation and if one is inserted before the 31, the solutions do not work.One way to make the question work is to rewrite the quadratic equation asx2 - 10x + 31 = 0 which requires adding 3 characters (all in bold).It is therefore impossible to be certain about the answer to your question. If that is the case, the radix is 13. Otherwise, please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared".
4(3x+6y = 42) 3(-7x+8y = -109) Multiply all terms in the top equation by 4 and in the bottom by 3: 12x+24y = 168 -21x+24y = -327 Subtract the bottom equation from the top remembering that a minus from a minus is equal to a plus: 33x = 495 Divide both sides by 33: x = 15 Substitute the value of x into the original equations to find the value of y: Therefore: x = 15 and y = -1/2
3x+2y-5=0 3x+2y=5 Im lost im only 12 work out the rest hope i helped
5 it is 5 because 13 + 7 = 20 20 divided by 4 is 5 to find out the answer, work through the equation backwards and use the opposite operations.
12 + 4*10 = 12+40 = 52
There are 2 unknowns
3-(-9) Considering a negative plus a negative equals a positive your equation can be rewritten as 3+9 Which equals 12
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
Good work ! Did you have a question you wanted to ask ?
The solutions work out as: x = 52/11, y = 101/11 and x = -2, y = -11
how do you use the substitution method for this problem 2x-3y=-2 4x+y=24
x-4+6=x This is equation is false because if you work it out you get 2=0 and two does not equal zero. And you cant take the sqrt of a false equation.
This is the equation for "work."
How do you work out 5a plus 7 equals 9? Put in equation form5a+7=9 subtract 7 from both sides gives you 5a=2divide 5 from both sides gives you a=2/5 or .4substitute in .4 for your a to check answer5(.4)+7=9
Chord equation: y = x+5 Circle equation: x^2 +4x +y^2 -18y +59 = 0 Chord end points: (-1, 4) and (3, 8) Chord midpoint: (1, 6) Perpendicular slope: -1 Perpendicular bisector equation: y-6 = -1(x-1) => y = -x+7
Their values work out as: a = -2 and b = 4
