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

Solve the system algebraically.<br> 3x - 2y - 1 = 0 y = 5x + 4 <br> What is the solution?
Bogdan [553]

Answer:

x=\frac{-9}{7}

y=\frac{-17}{7}

Step-by-step explanation:

We have been given the equation:

3x-2y-1=0

And y=5x+4

Second equation can be rewritten as:

5x-y=-4

We will solve the equations:

3x-2y=1      (1)

5x-y=-4       (2)

Multiply equation (1) by 5 and equation (2) by 3 we get:

15x-10y=5      (3)

15x-3y=-12       (4)

Now, subtract (4) from (3) we get:

-7y=17

y=\frac{-17}{7}

Now substitute y=\frac{-17}{7} in equation (1) we get:

3x-2{\frac{-17}{7}}=1

3x+\frac{34}{7}=1

21x=-27

x=\frac[-27}{21}

x=\frac{-9}{7}
