2x²+7x+6=6

Subtract 6 from both side we get

2x²+7x+6-6=6-6

The sum of two numbers is 72. The difference of the two numbers is 40. What are the two numbers.
Oxana [17]

Step-by-step explanation:

x + y = 72

x - y = 40

x = y + 40

so, the first equation is then

y + 40 + y = 72

2y + 40 = 72

2y = 32

y = 16

x = y + 40 = 16 + 40 = 56
