50 points What is the value of x?

Mathematics
1 answer:
Korvikt [17]4 years ago
3 0

Answer:

$x=-\frac{38}{9}$

The alternatives are not right.

Just take:

$27(x+4)=-6 \implies 27 \left(-\frac{38}{9} +4\right)=-6 \implies  27 \left(-\frac{38}{9} +\frac{36}{9} \right)=-6 $

$27 \left(-\frac{2}{9}  \right)=-6 \implies -\frac{54}{9}=-6 \implies -6=-6 $

Step-by-step explanation:

27(x+4)=-6

27x+108=-6

27x=-6-108

27x=-114

$x=\frac{-114}{27} $

$x=\frac{-114}{27} $

Multiply denominator and numerator by $\frac{1}{3} $.

$x=-\frac{38}{9}$

<span><span>DO use multiplication sign '*' (the STAR) symbol. For the simplifier, xy is NOT the same as x*y or yx. Simplifier thinks that xy is a separate variable. Good example: x*y-y*(x+2). Bad example: xy-y(x+2).</span>DO use '*' when multiplying a variable by an expression in parentheses: x*(x+2). Otherwise, my simplifier will think that you are trying to use a function and will become confused.Use parentheses liberally to avoid any ambiguity. (x+y)/(x-y) is NOT the same as x+y/x-y. x+y/x-y means x+(y/x)-y.</span>Operations<span>Use '*' (STAR) for multiplication. 2*3 is legal, 2x3 will be misunderstood.Use '^' (CARET) for power. 2^3 means 2 to degree of 3, or 8.Use '/' (FORWARD SLASH) for divisionOnly '(' and ')' (parentheses) are allowed for grouping terms. Curly or square brackets are used for other purposes.</span>

Operation priority: + and - have lowest priority, * and / h

Good Examplesx*y-x*(y+2) <-- '*' is used for multiplications a^b*3 <-- means (a to the degree of b) multiplied by 3 Bad examples<span>xy-yx <-- variable xy and variable yx are different variables y(x-2) <-- simplifier will think that it is function y of x-2.</span>
