Answer: x= -3

Step-by-step explanation: First you add 4.2x to both sides to get: 1.8+0.5x= 0.3. Then you subtract 1.8 from both sides and get: 0.5x=-1.5. Lastly, you divide by 0.5 both sides and get x=-3

Using arithmetic principle, the value of x in the equation given is 3

To solve, Equate the both equations, collect like terms and solve for x :

1.8 - 3.7x = - 4.2x + 0.3

Collect like terms

1.8 - 0.3 = -4.2x + 3.7x

1.5 = - 0.5x

Divide both sides by - 0.5

1.5/-0.5 = - 0.5x/-0.5

3 = x

Therefore, the value of x in the equation is 3.
