To find the answer:

4(x - 0.8) = 3.8x - 5.8 \\ 4x - 3.2 = 3.8x - 5.8 \\ 4x - 3.8x = - 5.8 + 3.2 \\ 0.2x = - 2.6 \\ x = - ( 2.6)/(0.2) \\ x = - 13

Therefore, x=-13.

Hope it helps!

Answer: The required solution is x = -13.

Step-by-step explanation: We are given to solve the following linear equation in variable x :


4(x-0.8)=3.8x-5.8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Solving equation (i) means finding the value of the unknown variable x.

The solution of equation (i) is as follows :


4(x-0.8)=3.8x-5.8\\\\\Rightarrow 4x-3.2=3.8x-5.8\\\\\Rightarrow 4x-3.8x=3.2-5.8\\\\\Rightarrow 0.2x=-2.6\\\\\Rightarrow x=-(2.6)/(0.2)\\\\\Rightarrow x=-13.

Thus, the required solution is x = -13.
