x÷4-30=x÷32/5
Answered by Anonymous
x / 4 - 30 = ( x / 32 ) / 5

x / 4 - 30 = x / ( 32 * 5 )

x / 4 - 30 = x / 160

40 x / 160 - 30 = x / 160

40 x / 160 - x / 160 = 30

39 x / 160 = 30 Multiply both sides by 160

39 x = 30 * 160

39 x = 4800 Divide both sides by 35

x = 4800 / 39

x = 3 * 1600 / ( 3 * 13 )

x = 1600 / 13

x = 123.076923

x÷4-30=x÷32/5
or
x/4- 30 = x(5/32)
multiply each term by 32

8x - 960 =5x
3x = 960
x = 320

check:
LS =320/4 - 30 = 50
RS = (320) ÷ (32/5) = 320 (5/32) = 50 = LS

my answer of x = 320 is correct.
