Question

{
x = 10
3x + 5y = 20
What is the solution (x, y)

Answer 1

x=10,y= -2).

Explanation:

The given system of equations is:

x = 10

3x + 5y = 20

We can use substitution to solve for y. Starting with the first equation:

x = 10

We can substitute the value of x into the second equation:

3x + 5y = 20

3 * 10 + 5y = 20

30 + 5y = 20

5y = 20 - 30

5y = -10

Finally, we can solve for y by dividing both sides of the equation by 5:

y = -10 / 5

y = -2

x=10,y= -2).
