2x = 18
x = 9
Answer:
-----×4 + 9
Step-by-step explanation:
The product is evaluated left-to-right. We don't know the meaning of -----× so we cannot combine it with anything.
-----×4×1/4×4+9 = -----×(4/4)×4+9
= -----×1×4 + 9
= -----×4 + 9
_____
We are assuming that -----× is equivalent to some variable, that it represents a blank containing a value unknown. If that is the appropriate interpretation, then the product of that unknown value and 4 cannot be combined with 9 until you know what value goes into the blank.
Answer: x=36
Step-by-step explanation: first, subtract 12 from both sides of the equation. X/2 + 12 = 84. X/2=72, then divide both sides of the equation by two to isolate the variable. X=36
