Question

solve the equation and check your result​

Answer 1

SOLVING THE EQUATION AND CHECKING THE RESULT

2.5(4x - 6) + 0.66(x + 2) = 7.8

Step.01 : Opening Brackets.

=> 10x - 15 + 0.66x + 1.32 = 7.8

Step.02 : Solving variable term and constant terms separately.

=> 10.66x - 13.68 = 7.8

Step.03 : Transposing variable to one side and constants to the other.

=> 10.66x = 21.48

Step.04 : Making the variable alone in one side to get its result.

=> x = 2.01 (approx)

VERIFICATION

LHS

2.5(4x - 6) + 0.66(x + 2)

= 2.5(8.04 - 6) + 0.66 (2.01 + 2)

= 2.5(2.04) + 0.66(4.01)

= 5.1 + 2.6466

= 7.7568

= 7.8 (approx)
