Question

The sum of four consecutive odd integers is -72. write an equation to model this situation. find the value of the four integers

Answer 1

odd integers are 2 apart

so
they are x,x+2,x+4,x+6

sum is -72
sum means add

x+x+2+x+4+x+6=-72
4x+12=-72
minus 12 both sides
4x=-84
divide both sides by 4
x=-21
x+2=-19
x+4=-17
x+6=-15


the numbres are -21,-19,-17,-15
