Q. Solve for all values of x in simplest form.31=∣10−3x∣Answer: x=
Understand absolute value equation: Understand the absolute value equationThe absolute value of a number is its distance from zero on the number line, regardless of direction. Therefore, ∣10−3x∣ can be either 10−3x or −(10−3x) if 10−3x is negative. We need to consider both cases to find all values of x.
Set up two equations: Set up two equationsSince the absolute value expression can be positive or negative, we set up two equations to solve for x:1) 10−3x=312) −(10−3x)=31
Solve first equation: Solve the first equationSolve 10−3x=31 for x:Subtract 10 from both sides:−3x=31−10−3x=21Divide both sides by −3:x=21/−3x=−7
Solve second equation: Solve the second equationSolve −(10−3x)=31 for x:First, distribute the negative sign:−10+3x=31Add 10 to both sides:3x=31+103x=41Divide both sides by 3:x=341x=13.666...
Combine the solutions: Combine the solutionsThe solutions from both equations are x=−7 and x=13.666…, which can also be written as x=341.
