Step-by-step explanation:
Substitution means to substitute a variable with the other variable in the equation.
Like, in this equation, y = -5x.
Substituting it in the equation y = 2x - 14, we get,
=> -5x = 2x - 14
=> -7x = -14
=> 7x = 14
=> x = 2
Now, putting value of x in y = -5x, we get,
y = -5 (2) = -10
