18
Step-by-step explanation:
Answer:
The positive solution is 2.4.
Step-by-step explanation:
The given functions are
It is given that
The quadratic formula:
Therefore the positive solution is 2.4.
Operations are performed according to the Order of Operations. Sometimes the mnemonic PEMDAS or BIDMAS is used to remind you what the order is.
P/B - parentheses/brackets. The content of these is evaluated first.
E/I - exponents/indices. Exponentiation is done first, right to left: a^b^c = a^(b^c).
MD/DM - multiplication and division are done in order of appearance, left to right. Each has equal priority, neither is done before the other unless it appears in the expression first. a/bc = (a/b)c. ab/c = (ab)/c
AS - addition and subtraction are done in order of appearance, left to right. Each has equal priority.
_____
When functions are involved (sin( ), log( ), sqrt( ), for example), their arguments are evaluated according to the order of operations, then the function is evaluated, then the remainder of the operations are performed. For example, sin(a)^2 = (sin(a))^2. Sometimes, this is written sin^2(a).
When functions are written without parentheses around their arguments, it must be assumed that the function only applies to the first entity following the function name. log ab+c/d = (log(a)*b)+(c/d), for example, or √3x = (√3)x.

<span>I would contact your instructor, because I think there may be a typo in the original problem. I worked it out and got x = -4 </span>The steps go like this:
1. Distribute the 3 to each of 1/3x and 1. This gives you <span>x + 3 + 4</span> on the left side. Simplify that to x + 7.
2. Distribute the -4 to each of x and 3. This gives you -1 - 4x - 12 on the right side. Simplify that to -13 - 4x. Now you have <span>x + 7 = -13 - 4x.</span>
3. Subtract 7 from both sides.
4. Add 4x to both sides. Now you have 5x = -20 (This is the step Antwon gets to)
5. Divide by 5. You get <span>x = -4
</span>
