Q. Solve for x and write your answer in simplest form.−23−(−21x+10)+x=9xAnswer: x=
Distribute and Combine Like Terms: Simplify the left side of the equation by distributing the negative sign and combining like terms.We have the equation: −(23)−(−(21)x+10)+x=9xDistribute the negative sign through the parentheses: −(23)+(21)x−10+x=9xCombine like terms: (21)x+x=(23)xNow the equation is: −(23)+(23)x−10=9x
Add to Isolate x Terms: Add (23) to both sides to isolate the x terms on one side.−23+23x−10+23=9x+23This simplifies to: 23x−10=9x+23
Add 10 to Isolate x Terms: Add 10 to both sides to further isolate the x terms.23x−10+10=9x+23+10This simplifies to: 23x=9x+23+10
Subtract to Combine x Terms: Subtract 23x from both sides to get all x terms on one side.23x−23x=9x+23+10−23xThis simplifies to: 0=9x−23x+23+10
Combine Like Terms: Combine like terms on the right side.0=9x−23x+23+10To combine the x terms, convert 9x to 218x so that we have a common denominator:0=218x−23x+23+10Now combine the x terms: 218x−23x=215xSo the equation is now: 0=215x+23+10
Subtract to Isolate x Term: Subtract (23) from both sides to isolate the x term.0−23=215x+23+10−23This simplifies to: −23=215x+10
Subtract to Isolate x Term: Subtract 10 from both sides to completely isolate the x term.−23−10=215x+10−10This simplifies to: −23−10=215x
Combine Numbers on Left: Convert −10 to a fraction with a denominator of 2 to combine with −(3)/(2). −10=−(20)/(2)Now the equation is: −(3)/(2)−(20)/(2)=(15)/(2)xCombine the numbers on the left side: −(23)/(2)=(15)/(2)x
Divide to Solve for x: Divide both sides by (215) to solve for x.x=(215)−(223)To divide by a fraction, multiply by its reciprocal: x=−(223)×(152)
Simplify the Fraction: Multiply the numerators and denominators. x=2×15−(23)×2This simplifies to: x=30−46
Simplify the Fraction: Multiply the numerators and denominators.x=2×15−(23)×2This simplifies to: x=30−46 Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2.x=(30/2)(−46/2)This simplifies to: x=15−23
