Answer:
y = -30
Option A
Step-by-step explanation:
y = -2x - 10
y = -5x + 20
We just need to substitute the values of y.
We have to equate both the equation.
-2x -10 = -5x + 20
-2x + 5x = 20 + 10
3x = 30
x = 10
Plug x as 10 in any one of the equation
Let's take the first equation
y = -2x - 10
y = -2(10) - 10
y = -20 -10
y = -30
