2X+(X+1)=46
2X+X+1=46
3X=46-1
3X=45
X=45/3
X=15 ANSWER FOR THE FIRST INTERGER &
15+1=16 FOR THE SECOND INTERGER.
PROOF
2*15+16=46
30+16=46
46=46

Find two consecutive intergers such that twice the first interger plus the second interger equals 46.

What is asked in the problem?
find two consecutive integers
Given:
twice the first plus the second integer equals 46
Representation:
Let n be the first integer
n + 1 be the second integer
Equation:
2n + n + 1 = 46 combine like terms
3n + 1 = 46 Subtract 1 both sides
3n = 45 divide 3 both sides
n = 15 First integer
n + 1 = 15 + 1
= 16 Second integer

CHecking :
2(15) + 16 = 46
30 + 16 = 46
46 = 46 ----> True
