The sum of 2 and three times a number equals 11. find the number.

-5

Step-by-step explanation:

x = first number

y = second number

From the first sentence

11 = 2x + 3y

From the second sentence (I'm assuming the word "dust" should be "first"

y = 2-x

rewritten as  

x + y = 2

So your system of equations is

2x + 3y = 11

x  +  y  =  2

Multiply the 2nd equation by -2

2x + 3y = 11

-2x - 2y = -4

Add the two equations together

y = 7

Use y=7 to solve for x

x = 2-y = 2-7 = -5

2.2x5=11

Step-by-step explanation:

11 divided by 5 equals 2.2.

2.2x5=11
