Question

4. What is the value of x in the equation below?
14.3 -0.4x = 2.6x + 5.6​

Answer 1

x = 2.9.

Explanation:

14.3 - 0.4x = 2.6x + 5.6​

14.3 - 5.6 = 2.6x + 0.4x

8.7 = 3x

x = 8.7 / 3 = 2.9 (answer).

Answer 2

x=2.9

Explanation:

14.3 -0.4x = 2.6x + 5.6​

Add .4x to each side

14.3 -0.4x+.4x = 2.6x+.4x + 5.6​

14.3 = 3x+5.6

Subtract 5.6 from each side

14.3 - 5.6 = 3x - 5.6

8.7 =3x

Divide each side by 3

8.7/3 = 3x/3

2.9=x
