Question

If 85 1/2-64 x/8= 21 1/8 then find the value of x

Answer 1

Answer:

Step-by-step explanation:

85*1/2-64*x/8=211/8

85/2-8x=211/8

85-16x/2=211/8

85-16x=211/8*2

85-16x=211/4

-16x=211/4-85

-16x=-129/4

x=129/4*1/16

  =129/64

x=129/64

Answer 2

Step-by-step explanation:

$85 \frac{1}{2} - 64 \frac{x}{8} = \frac{211}{8}$

$\frac{211}{8} - \frac{85}{2} = 64 \frac{x}{8}$

$\frac{211}{8} - \frac{340}{8} = 64 \frac{x}{8}$

$\frac{129}{8} = \frac{64x}{8}$

$\frac{64x}{8} - \frac{129}{8} = 0$

$\frac{64x - 129}{8} = 0$

${64x} - 129 = 0$

$64x = 129$

$x = \frac{129}{64}$
