[Given]
{ x + y = 6
{ x = y + 4
[Plug-in our x value & solve]
[Given] x + y = 6
[ Plug-in] (y + 4) + y = 6
[Distribute] y + 4 + y = 6
[Combine like terms] 2y + 4 = 6
[Subtract 4 from both sides] 2y = 2
[Divide both sides by 2] y = 1
[Answer]
Third option - (5, 1)
-> You do not need to solve for x since this is the only option that has y = 1, but to solve for x we would do y + 4 = 1 + 4 = 5, so this answer fully checks correctly

Answer:
2 7/16 inches longer
Step-by-step explanation:
15 3/16 - 12 3/4= 243/16 - 51/4 = 243/16 - 204/16= 39/16 inches longer
39/16=2 7/16 inches longer
Solve the 2 equations then if : X and Y are positive then it is the first quad
if X is negative and Y is positive then it is in second quad
if X is negative and Y is negative then it is 3rd quad
if X is positive and Y is negative then it is the 4th quad
(look at the signs of numbers solved by the equation)
