The sum of two numbers is 46. The larger number is two less than three times the smaller number. Find the numbers.

melamori03 [73]

Answer: The numbers are: <u>x = 34, y = 12</u>

Step-by-step explanation:

Lets say the numbers are x and y. The two equations are:

x+y=46

x= 3y-2

Next you use substitution for x in the first equation which brings you to

3y-2 + y = 46 which simplyfies to:

4y - 2 = 46

4y = 48

48 / 4 = 12

y = 12

Then you plug back y=12 in either of the equation to solve for x:

x = 3y - 2

x = 3(12) - 2 = 36 - 2 = 34

x = 34, y = 12

What is the value of x in the equation 3x-4y=65, when y equals 4?

andreev551 [17]

Answer:

x = 27

Step-by-step explanation:

3x - 4y = 65

3x = 65 + 4y

<em><u>Find x, when y = 4</u></em>

3x = 65 + 4 (4)

3x = 65 + 16

3x = 81

x = 27 $[ \ x = \frac{81}{3}\ ]$
