Answer:
The value of y is:
\(y=3x-1.5\)
Step-by-step explanation:
We are given a equation in terms of variable x and y as follows:
\(4.2x-1.4y=2.1\)
Now, we are asked to solve for y i.e. we are asked to find the value of y in terms of x and constant.
Now, we subtract 4.2x on both the sides of the equation to obtain:
\(-1.4y=2.1-4.2x\)
On dividing both side of the equation by (-1.4) we get:
\(y=\dfrac{2.1}{-1.4}-\dfrac{4.2x}{-1.4}\\\\y=-1.5+3x\\\\i.e.\\\\y=3x-1.5\)
