Question

Evaluate for 'x' if 6.2 x = 8.1 X 8.1 - 1.9 X 1.9​

Answer 1

Step-by-step explanation:

6.2x = 8.1 X 8.1 – 1.9 X 1.9

6.2x = 65.61 – 3.61

6.2x = 62

x = 62 ÷ 6.2

x = 10

The value of "x" is 10

Answer 2

ANSWER:

$6.2x = 8.1 \times 8.1 - 1.9 \times 1.9 \\ = > 65.61 - 3.61 = 62 \\ 6.2x = 62 \\ therefore \: x = \frac{62}{6.2} \times \frac{10}{10} = \frac{620}{62} = 10 \\ x = 10$

CONCLUSION:

The Value of x if 6.2x = 8.1 × 8.1 - 1.9 × 1.9 is = 10

VERIFICATION:

$substitute \: x = 10 \\ = > 6.2(10) = 8.1 \times 8.1 - 1.9 \times 1.9 \\ = > 62 = 65.61 - 3.61 \\ = > 62 = 62$

THEREFORE, It is Verified that LHS is Equal to RHS.
