Algebra:

x + y = 12

x = y + 2

y + y + 2 = 12

2y + 2 = 12

2y = 10

y = 5

x = 5 + 2 = 7

5 and 7 (D)

Logic:

Out of the numbers given, which two numbers add up to 12? only 5 & 7

To check, Is one of the numbers 2 more than the other? yes, 7 is 2 more than 5.

Hey there!!

Let's take the number as x and y

Given,

The sum of x and y = 12

One number is 2 more than the other

Let's take y = x + 2

Equations

x + y = 12

As we know y = x + 2 , plug the value in

x + x + 2 = 12

2x + 2 = 12

Subtract 2 on both sides

2x = 10

Divide by 5 on both sides

x = 5

y = 2 + x

y = 7

The numbers are 5 and 7

Hope my answer helps!

12x - 84 = 4x + 12. What does X equal?

Vesnalui [34]

Answer:

Step-by-step explanation:

To solve the problem, you have to leave the x alone,

To do so, you have to add 84 on each side

12x = 4x + 96

Then, subtract 4x on each side,

8x = 96

Then divide each side by 8, so

x = 12

Hope it helps!!

Let me know if I'm wrong or you need help on anything else!!

Also, if you're okay with it, can you plz make be brainliest?

Solve the system of equations x - y = 12 and x + 7y = -20 by combining the<br> equations.

iogann1982 [59]

Answer:

x=16, y=-4

Step-by-step explanation:

-1(x-y=12)

x+7y=-20

-x+y=-12

x+7y=-20

8y=-32

y=-4

x-4=12

x=16

A)<br> Identify all x-values not in the domain of<br> y=(x² – 4x²) / (3x² - 6x – 24)

True [87]

Answer:

x ≠ 4 or -2

Step-by-step explanation:

the denominator cannot be zero, so factor the bottom equation to get the zeros and those are the domain restrictions.

3x^2 - 6x - 24 ≠ 0

3(x^2 - 2x - 8) ≠ 0 (factor out a 3)

3(x - 4)(x + 2) ≠ 0 (factor equation)

x ≠ 4, x ≠ -2 (use zero product property to find zeros)

the sum of two numbers is 70. the larger number is five less than twice the smaller number . what are the two numbers

earnstyle [38]

X+y=70
x=2y-5
x=larger number
y=smaller number
now plug in the value of x to only have one variable in the equation...
Way to solve for y:
(2y-5)+y=70
3y-5=70
add 5 on both sides...
3y=75
divide by 3 on both sides
y=25
1st way to solve for x:
now plug in y in the original equation...
x+25=70
subtract 25 on both sides...
x=45
2nd way to solve for x:
plug in y for the second equation...
x=25(2)-5
x=50-5
x=45
answer: the two numbers are 45 and 25.
