Question

3.8 x 53 = (8 x ?) + (8 x 2)
8 x 53= ?+ ?
8 x 53 =
?

Answer 1

> x = 7,

Explanation:

Answer:

3x - 8(3-x) = 53

==> 3x - 8*3 + 8*x = 53

==> 3x - 24 + 8x = 53

==> 11x - 24 = 53

Add 24 on both sides...

==> 11x - 24 + 24 = 53 + 24

==> 11x = 77

Divide both sides by 11

==> x = 7, which is the required solution.

Hope you found the explanation useful.
