Answer:

4b+8 = 20

---------------

4b = 20

-------------------

b = 5

Step-by-step explanation:

We need to solve for b in the following equation:

$\frac{4b + 8}{2} = 10$

When we multiply each term by 2 the denominator cancels out:

$\displaystyle 2 \times \frac{4b + 8}{2} = 10 \times 2\\\\4b + 8 = 20$

Next, we subtract 8:

$4b +8 - 8 = 20 - 8\\4b = 20$

Final step, we isolate the variable. We cancel the multiplication on the left side when dividing by 4 on each term

$\displaystyle 4b = 20\\\\\frac{4b}{4} = \frac{20}{4}\\\\b = 5$

Kevin is 4 times as old as Daniel and is also 6 years older than Daniel

MAXImum [283]

Answer:

Part a) Daniel's age is 2 years

Part b) Kevin's age is 8 years

Step-by-step explanation:

The question is

Part a) How old is Daniel?

Part b) How old is Kevin?

Let

x ----> Kevin's age

y ----> Daniel's age

we know that

$x=4y$ -----> equation A

$x=y+6$ ----> equation B

Equate equation A and equation B

$4y=y+6$

solve for y

$4y-y=6$

$3y=6$

$y=2$

therefore

Daniel's age is 2 years

Find the value of x

substitute the value of y in any of the two equations

$x=4(2)=8\ years$

$x=2+6=8\ years$

therefore

Kevin's age is 8 years
