Answer 2

0.2x + 0.09 = 0.11 + 2.07

0.2x - 0.11x = 2.07 - 0.9

0.9x = 1.17

$\frac{0.09x}{0.09} = \: \frac{1.17}{0.09} \\ \\ x = 13$

HENCE X = 13 IS THE SOLUTION OF THE GIVEN EQUATION.

______________________________________________________

verification:-

substituting x = 13 in the given equation we get

LHS = 0.2 × 13 + 0.9 = 2.6 + 0.09 = 3.5

RHS = 0.11 × 13 + 2.07 = 1.43 + 2.07 = 3.5

LHS = RHS

✅Hence the solution is thus checked for its correctness
