.30(8)+1.00(x)=.60(8+x)

x = 6

Step-by-step explanation:

Simplify by multiplying and distributing:

.30(8) + 1.00(x) = .60(8 + x)

2.4 + x = 4.8 + 0.6x

Solve for x:

x = 2.4 + 0.6x

0.4x = 2.4

x = 6

So, the answer is x = 6

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
