Let x and y be the two numbers. Then by assumptions we have x+y=30 and x-y=20. Hence, y=x-20 and by plugging this into the first equation we obtain x+x-20=30 or 2x=50 or x=25 and y=5
Step-by-step explanation:
So, divide 30 by 2 . That gives you 15 for x, 15 for y. Now, you have difference of six, divide by two, that equals 3.
u just gotta mutiply the 3 to both the 8 and x making 24+x then u put the 12 then I got the equation 24+x+12 then add like numbers so the only onea u got are 12 and 24 which make 36 and left with 3x so ur solution is 36+3x
