Answer:


x=-6(7)/(8)

Explanation:


Solve\:9\:(1)/(4)\:+\:x\:=\:2\:(3)/(8)

Step 1:
Convert all mixed fractions to improper fractions.
This will make it easier to add and subtract

Mixed fraction
a(b)/(c) can be converted to an improper fraction using


a(b)/(c)=(a\cdot \:c+b)/(c)


9(1)/(4)=(9\cdot 4+1)/(4) = (37)/(4)


2(3)/(8)=(2\cdot 8+3)/(8) =(19)/(8)

Step 2:
Replace every mixed fraction in the original equation with its equivalent improper fraction:

(37)/(4)+x=(19)/(8)

Step 3
Solve for x


  • \mathrm{Move}\:(37)/(4)\:\mathrm{to\:the\:right\:side}:

    (37)/(4)+x-(37)/(4)=(19)/(8)-(37)/(4)
  • Simplify:

    x =(19)/(8)-(37)/(4)
    To calculate the right side value, multiply
    (37)/(4) by 2 on both numerator and denominator. This will get the denominator as 8 for both fractions and we can simply subtract the numerator:


    \begin{aligned}x & = (19)/(8) - (37 * 2 )/(4 * 2) \\ & = (19)/(8) - (74)/(8)\\& = (19 - 74)/(8)\\& = - (55)/(8)\\\end{aligned}\\\\

  • \mathrm{Convert\:to\:mixed\:number:\:Quotient(Remainder)/(Divisor)}
    55 goes into 8 six times so the whole part(quotient) is 6
    Remainder = 55 - 8 x 6 = 55 - 48 = 7
    So the fractional part = remainder/divisor = 7/8
  • Result:

    x=-6(7)/(8)
