Find four consecutive even integers such that if the sum of the first and third is multiplied by 3, the result is 28 less than f

WITCHER [35]

Answer:

$A=-10\\B=-8\\C=-6\\D=-4$

Step-by-step explanation:

We can solve the problem in this way:

- The 1st information that we have is that the four numbers are even and consecutive integer. Let's call these numbers A, B, C and D. This means that:

$D=C+2\\C=B+2\\B=A+2$

(since the distance between two even consecutive numbers is 2)

- The 2nd information that is given is that the sum of the first and third multiplied by 3 equals 28 less than 5 times the fourth, so:

$3(A+C)=5D-28$ (1)

Now we rewrite eq(1) by using:

$D=C+2$

and

$A=C-4$ (obtained by combining the 3 first equations)

So we get:

$3(C-4+C)=5(C+2)-28$

Solving this equation for C,

$6C-12=5C+10-28\\C=-6$

So the other numbers are:

$A=-10\\B=-8\\C=-6\\D=-4$
