Question

Solve the equation.

( - 10.3) (2)x = 4 (- 10.3) (2)

A. -20.6

B. 4

C. -41.2

D. 2

Answer 1

The answer is B. 4

Explanation:

To solve this you work out the right side first by multiplying 4*(-10.3)*2= -82.4 making the equation (-10.3)*2*x=-82.4. Multiply 2 *(-10.3)= -20.6. (-20.6)*x=-82.4. Then because (-20.6) is multipled by x to get -82.4, you must divide both sides by -20.6, Making it x=4
