What are two consecutive integers that have a sum of -67

valkas [14]

Answer:

The two integers are -34,-33

Step-by-step explanation:

x 1st integer

x+1 2nd integer

The sum is -67

x+x+1 = -67

Combine like terms

2x+1 = -67

Subtract 1 from each side

2x+1-1 = -67-1

2x= -68

Divide by 2

2x/2 = -68/2

x = -34

x+1 = -34+1 = -33
