Answer:
<h2>The answer is option B</h2>
Step-by-step explanation:

To solve it first of all cross multiply
That's
x + 4 = 6
Move 4 to the right side of the equation
The sign changes to negative
That's
x = 6 - 4
We have the final answer as
<h3>x = 2</h3>

Answer:
<h2>u = 2T - v</h2>

Cross multiply
We have
2T = u + v
u + v = 2T
Move v to the right side of the equation to make u stand alone
We have the final answer as
<h3>u = 2T - v</h3>

Answer:
the numbers are 20 and 24
Step-by-step explanation:
The numbers are in the ratio 5 : 6 = 5z : 6z , where z is a multiplier
The numbers sum to 44, thus
5z + 6z = 44
11z = 44 ( divide both sides by 11 )
z = 4
Hence
5z = 5 × 4 = 20
6z = 6 × 4 = 24
The two numbers are 20 and 24
