Question

find the value of x when 7/x+35=1/10

Answer 1

Answer: 35

7/x + 35 = 1/10

Cross multiplying,

7 × 10 = (x + 35) × 1

70 = x + 35

x = 70 - 35

x = 35

Answer 2

Answer:

7/x +35 = 1/10

7/x = 1/10-35

7/x = (1-350)/10

7/x = -349/10

by cross multiplication

7×10 = -349x

-349x = 70

x = -70/349

verification

7÷(-70/349) +35 = 1/10

(7×349/-70)+35 = 1/10

-34.9+35 = 1/10

0.1 = 1/10

1/10= 1/10

lhs = rhs
