Answer 2

Answer:

Step-by-step explanation:

7x − 7y = 18

solve for x when y= -6

first we need to plug in -6 to the equation so

7x - 7 (-6) = 18

then we need to simplify by multiplying what we know

7x - (-42) = 7x + 42

7x + 42 = 18

     -42    -42

7x = -24

divide both sides by 7

x = - 3.4
