.............​

Answer 1

Answer:

follow me

Step-by-step explanation:

x/2+x/42=12

take lcm

21x+x/42=12

take 42 to right hand side

21x+x=12+42

22×=504

x=504/22

x=23 approx.

Answer 2

Answer:

x / 2 + x / 42 = 12

Multiply both sides of the equation by 42, the least common multiple of 2,42.

21x+x=504

Combine 21x and x to get 22x.

22x=504

Divide both sides by 22.

x=\frac{504}{22}

Reduce the fraction \frac{504}{22} to lowest terms by extracting and canceling out 2.

x=\frac{252}{11}
