Four friends were born in consecutive years. The sum of their ages is 94. What is the age of the oldest friend?

Savatey [412]

Hello,

We don't need algebra to solve this.

I suppose the ages are 1,2,3,4
Their sum is 1+2+3+4=10.
To obtain 94 we must add 94-10=84 for 4 persons =>84/4=21 to each

Ages are
1+21=22
2+21=23
3+21=24
4+21=25

But if really want an algebric resolution:

Let's x the age of the youngest
x+1,x+2,x+3 the others.

x+(x+1)+(x+2)+(x+3)=94
==>4x+6=94
==>4x=88
==>x=22
Ages are 22,23,24,25.

The oldest friend is 25 years old.

Some steps in solving an equation are more efficient than others. Complete parts (a) though (d) to determine the most efficient

Vinil7 [7]

Answer:

The solution of the given equation x =11

Step-by-step explanation:

Given equation 34 - 5x = -21

Step :-(a)

Given equation 34 - 5x = -21

Subtracting '34' on both sides , we get

34 - 5x -34 = -21 -34

Step:-(b)

on simplification , we get

-5x = -55

Step:-(c)

Dividing ' -5' on both sides , we get

$\frac{-5x}{-5} =\frac{-55}{-5}$

Cancellation '-5' on both sides , we get

x = 11

Step :-(d)

The solution of the given equation x =11
