Hi there !

Question:

0.3x + 0.4 = 0.28x + 1.16

Solution:

0.3x + 0.4 = 0.28x + 1.16

=> 0.3x - 0.28x = 1.16 - 0.4   [by transposition]

=> 0.02x = 0.76

=> x = 0.76 / 0.02

=> x = 76 / 2

=> x = 38

∴ x = 38 is a solution of the given equation.

VERIFICATION ;

-------------------------

By substituting the value of x = 38 in the given equation,

We get ;

0.3x + 0.4 = 0.28x + 1.16

=> 0.3 × 38 + 0.4 = 0.28 × 38 + 1.16

=> 11.4 + 0.4 = 10.64 + 1.16

=> 11.8 = 11.8​

.·. LHS = RHS.

Hence, x = 38 is the solution of the given equation.

Thanks for the question !

Answer 2

0.3x + 0.4 = 0.28x + 1.16

0.3x - 0.28x = 1.16 - 0.4

0.02x = 0.76

x = 0.76 / 0.02

x = 38
