Question

Solve bottom 2 please Algebra 1

Answer 1

Q1: If we assume that the smaller consecutive integer equals to N, then the greater integer becomes N+1 (cuz they r consecutive). So we work out the following equation:
N+N+1= 3N-1
Then we move all the variables to one side:
2N+1= 3N-1
1+1= 3N-2N
N=2
N+1=3

Check:
2+3=3*2-1
5=5
Correct
