find x given that y=10

y=8-4x

Substitute 10 for y in the second equation so that:

10=8-4x

now solve for x

Put y=10

we have
10=8-4x
subtract 8 both sides we get
2=-4x
or x=-2/4 =-0.5
This answer

To solve for x when y=10, you need to substitute the value of y into the equation y=8-4x and then solve for x.

Let's substitute y=10 into the equation:

10 = 8 - 4x

Next, we can simplify the equation by adding 4x to both sides:

4x + 10 = 8

Now, let's isolate the variable term by subtracting 10 from both sides of the equation:

4x = 8 - 10

This simplifies to:

4x = -2

Finally, we can solve for x by dividing both sides of the equation by 4:

x = -2/4

So, the value of x when y = 10 is x = -1/2.
