Tripling the greater of two consecutaive even intergers give the same result as subtracting 10 from the lesser even integer. What are the intergers?

Number theory? More like algebra 1.
2 even numbers are 2*n & (2*n +2)
3*(2*n+2) = 2*n - 10
6*n + 6 = 2*n - 10
4*n = -16
n = -4
-8, -6 are two numbers

Don't you have to just love word problems in math?
Let X = the lessor number X+2 the larger
3(X+2)=X-10 3X+6=X-10 (subtract X)
2X+6= -10 (subtract 6) 2x=-16 x=-8
Proof: 3(-6)=-8 -10 -18 = -18
Two consecutive even numbers are -8 and -6.
Looks good to me.

first of all, none of that makes any sense to me, but I can tell you that an integer is any positive number, negative number, or zero
these are integers:
5; -4; 149,006,953; -42; 0; 100
these aren't integers:
1/2; 0.25; 87.83333...; 1,003 3/8
