x=4From superscot85: How you solve it is to subtract 4 from each side leaving x = 4
5x+3 = x+4 5x-x = 4-3 4x = 1 x = 1/4 Thats not even close to how you solve it. First of all the equation is written 5^(x+3)=x+4. Simple Logarithms are needed to solve.
minus 5
1 + 3x - x = x - 4 + 2x 1 + 4 = x + 2x - 3x + x 5 = x
x=4 x=0
172=x
The answer to the math problem x 3-2x 2 plus x-4 0 is 0.
5 + (-4) = 1 x = -4
To solve x + x + x + x, set the problem up as multiplication like this 4x = 128. Divide both sides of the problem by 4. You will get x = 32. To check your work, substitute 32 for the x and do the math. 4 x 32 = ?. If the answer is 128, the answer is correct.
x = 6
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
