3 0

Answer:

n = 6

So,

19 = 5(6) + 7 - 3(6)

19 = 30 + 7 - 3(6)

19 = 30 + 7 - 18

19 = 37 - 18

19 = 19

Hope this helps!

WILL GIVE BRAINLIEST. If x+y=3 and 3x+5y=13, then x-y is equal to?
Alex17521 [72]

Answer:

(1,2)

y=2

x=1

Step-by-step explanation:

x+y=3

3x+5y=13

solve the equation

x=3-y

3x+5y=13

substitute the value of x into an equation

3(3-y)+5y=13

distribute

9-3y+5y=13

add -3y to 5y

9+2y=13

subtract 9 from both sides

2y=4

divide both sides by 2

y=2

substitute the value of y into an equation

x=3-2

subtract 3 to 2

x=1

--------

(1,2)

--------
