# Steps

1. Substute the known number into the equation. 6*-5+5y=20
2. Solve for the unknown variable, in this case y
3. Place the solution into the correct column, the first column for x and second for y

1. (-5, -10)

$$6·−5+−5y=20$$

Solution:

$$\left\{-10\right\}$$

$$2.\ (0\ ,-4)$$

$$6x+-5\cdot-4=20$$

Solution:

$$\left\{0\right\}$$

$$3.(5,2)$$

$$6x+-5\cdot2=20$$

Solution:

$$\left\{5\right\}$$
