Question

solve for x and y : x+y=14 and x-y=4

Answer 1

Answer:

x = 9 , y = 5

Step-by-step explanation:

add both eq,

x + y + x - y = 14 + 4

2x = 18

x = 9

y = x - 4

= 9 - 4

= 5

Answer 2

Answer:

$x + y = 14 \\ x - y = 4 \\ - - - - - \\ 2x = 18 \\ x = \frac{18}{2} \\ \large x = \bf \underline{ \underline{ 9}} \\ \\ x + y = 14 \\ 9 + y = 14 \\ y = 14 - 9 \\ \large y = \bf \underline{ \underline{ 5}}$
