Question

I need help, First question ever asked here, hope this helps!
Solve for y, then find the value of y when given x=-2
6x=7-4y
I tried going at it from all ends. How do I work through it?

Answer 1

When x = -2

6x = -12

So 12 = 7 - 4y

hence ... can you take it from here?

Answer 2

Solve for 'y first I suppose

\[\large 6x = 7 - 4y\]

Subtract 7 from both sides of the equation

\[\large 6x - 7 = -4y\]

Divide both sides by -4

\[\large y = \frac{6x - 7}{-4}\]

Now just plug in x = -2

\[\large y = \frac{6(-2) - 7}{-4} = \frac{-12 - 7}{-4} = ?\]
