Complete the missing value in the solution to the equation.

y=-2x+4

y=-2

X=3, y=-2

Step-by-step explanation:

This is a simultaneous equation question and we will have to solve using substitution method

So let's solve

y=-2x+4 ... (1)

y=-2 ... (2)

Let's substitute (2) into (1)

-2=-2x+4

Substrate 4 from both sides

-6=-2x

Divide both sides by-2

x=3

Substitute the value of x in (1)

y=-2 (3) + 4

y=-6+4

y=-2

Therefore x is 3, y is - 2
