X – 10y = 18 -6x – 10y = 32

Mathematics
1 answer:
viva [34]3 years ago
8 0

Answer:

Step-by-step explanation:

x - 10y = 18

-6x - 10y = 32

Since both equations have -10y, we can subtract the second equation from the first to try and solve for x:

(x - 10y) - (-6x - 10y) = 18 - 32

x - 10y + 6x + 10y = -14

7x = -14

x = -2

With this, we can plug the value back into the first equation to solve for y:

(-2) - 10y = 18

-2 - 10y = 18

-10y = 20

y = -2

Therefore, the solution is x = -2, y = -2

How do you differentiate linear equation from those equatipn which are not linear?​
dedylja [7]

Answer:

the x

Step-by-step explanation:

Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).

When you look at graphs that aren't linear, the x doesn't stand alone in the equation.

Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.

To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.
