Three consecutive even integers have a sum of 42. Find the three integers. What is the variable equation and solution
Let the first even integer be x.
The second even integer is x+2.
The third even integer is x+4.
\(x+x+2+x+4=42 \\
3x+6=42 \\
3x=36 \\
x=12 \\ \\
x+2=12+2=14 \\
x+4=12+4=16\)
The three integers are 12, 14 and 16.
