What is the correct first step for solving the equation 5x plus 3 equals 8?
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
What is the radix of the numbersif the solution to the quadratic equation x2-10x 31 is x equals 5 and x equals 8?
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".
What is 3x plus 6y equals 42 and -7x plus 8y equals -109 please use elimination and show work Thanks?
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
What is the answer to 3x plus 2y - 5 equals 0 x equals y plus 10?
3x+2y-5=0 3x+2y=5 Im lost im only 12 work out the rest hope i helped
In the equation 4x-7 equals 13 solve for x?
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.
