Simplify x plus 5 plus 3x - 7 plus 9x plus 3 - 4x?
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
X plus 5 plus 3x - 7 plus 9x plus 3 - 4x?
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9
How do you simplify a expression?
You write it out with less digits but will be able to get the same answer. Example: 9(x+3)=9x+27
What is the answer to 12x plus 6 equals 9x plus 27?
12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!
How do you simplify the rational expression x over 9x to the 8th power times x to the 7th power times 45 over x to the 4th power?
