Answer:

11 , 33

Step-by-step explanation:

Write out the equation

2x + 11 + x = 2(2x + 11 - x)

Simplify

3x + 11 = 4x + 22 - 2x

3x + 11 = 2x + 22

Solve for x

3x = 2x + 11

x = 11

Now we have x, find the other number

2(11) + 11 = 33

11 and 33 are the two numbers.

Okay, so 
a=2b+11 
<span>a+b = 2(a-b) </span>

<span>now solve </span>

<span>a+b = 2a-2b </span>
<span>3b = a, put that into the 1st equation: </span>

<span>3b = 2b+11 </span>
<span>b=11 </span>
<span>a = 2(11) +11 = 33 </span>

<span>check in the 2nd equation: </span>
<span>33+11 = 2(33-11) </span>
<span>44 = 2(22) </span>
<span>44 = 44</span>

Find the value of x in the equation below.<br> 48 = 6x
Akimi4 [234]

Answer:

x=8

Step-by-step explanation:

This is a simple one-step algebraic equation. In algebra, to find x you must isolate the variable. To do this, use the property of equality. This property states that an equation is still true if you do the same thing to both sides. For example, the equation would still be true if you added 1 to both sides.

To isolate x divide both sides by 6. This equals 48/6 = 6x/6. Which simplifies to 8=x.
