If the product of some number and 4 increased by 7 equals 3 then what is the number?
-1 Here is why: let x be the number, 4x+7=3 4x=3-7=-4 so 4x=-1 and x is -1
How do you solve that problem 4x-3-5x plus 7 equals 6?
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
What is 4x2-13x-12 divided by 4x plus 3?
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
What is the value of x in the equation 3 over 4x plus 2 equals 5 over 4x-6?
If the questions asks: (3)/(4x+2) = (5)/(4x-6) then x = -(7/4)
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
What does it mean to evaluate a formula?
To evaluate a formula is to try and solve or simplify it. For instance f(x) = 2x*4x-1x+6 f(x) = 7x+6 f(3) = 7*3+6
What is the value of 4x 3 when x 7?
4x + 3, where x = 7 4(7) + 3 = 28 + 3 = 31
How do you solve 5 plus 4x - 7 equals 4x plus 3 - 1x?
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
5x-10 equals -7 plus 4x?
x=3 That wasn't hard at all. 5x-10=-7+4x -4x -4x _____________ x-10=-7 +10 +10 _____________ x=3
What is the answer to -4x7?
3
What is the answer to 4x-5 equals 7?
4x-5=7 4x=12 x=3
What is the answer to 5 plus 4x-7 equals 4x plus 3-x?
5 + 4x - 7 = 4x + 3 - x (eliminate alike terms in both sides)5 - 7 = 3 - x (leave the variable alone by itself)5 - 7 - 3 = 3 - 3 - x-5 = -x (multiply both sides by -1)5 = x
Factor x squared - 4x - 21?
-17
What is the answere to 6(x 3)-(4x-7)?
If you mean: 6(x+3)-(4x-7) then it can be simplified to 2x+25
4x-3x plus 7equals -3?
4x - 3x + 7 = -3 x = -3 - 7 = -10
What is the answer for 4x plus 7 equals 3?
If 4x + 7 = 3... then x must equal -1
What is 3 over 4 x minus 4 equals 7 plus 1 over 2 x?
3/4x - 4 = 7 + 1/2x 3/4x = 11 + 2/4x 1/4x = 11 x = 44
