Question

Solve this system of equations by graphing.

Answer 1

• A. (-5,0)

Explanation:

-2x+5y = 10

y = x+5

Let's substitute " y = x+5":-

• -2x+5(x+5)=10

Simplify:-

• 3x+25 = 10

Subtract 25 from both sides:-

• 3x = -15

Divide both sides by 3:-

• 3x/3 = -15/3

• x = -5

Now, for y = x+5 substitute " x = -5":-

• y = -5+5

Simplify:-

• y = 0

Therefore, the solutions to the system of equations which be (-5,0).
