Answer 2

To solve the equation -0.9x + 2y - 2 = -1.4x + 7y, you can first simplify it by moving like terms to the same side of the equation. Let's start by adding 0.9x to both sides and subtracting 2y from both sides to isolate x terms on one side and y terms on the other side:

-0.9x + 2y - 2 + 0.9x - 2y = -1.4x + 7y + 0.9x - 2y

Now, simplify the equation:

-2 = -1.4x + 7y + 0.9x - 2y

Next, combine like terms:

-2 = (-1.4x + 0.9x) + (7y - 2y)

Now, combine the x and y terms:

-2 = (-0.5x) + (5y)

To solve for y, isolate the y term:

5y = -2 + 0.5x

Now, divide by 5:

y = (-2 + 0.5x)/5

So, the solution to the equation is:

y = (-2 + 0.5x)/5
