Express the equation x = 10 and y = -3 as a linear equation in two variables
34kurt

Answer:

For x = 10:

x + 0y - 10 = 0

For y = - 3:

0x + y + 3 = 0

Step-by-step Explanation:

Before we start let's recall the formula for the linear equations.

ax + bx = c

So first let's solve for x=10:

x = 10

Move 10 to the other side.

x - 10 = 0

As there is no y given we will simply write 0y.

x + 0y  - 10= 0

Now let's solve for y=-3:

y =  - 3

Move -3 to the other side.

y + 3 = 0

As there is no x given we will simply write 0x.

0x + y + 3 = 0

If this answer helped you, give this answer a heart, rate it and if you could then please mark it brainliest. Thanks!
