If: x+y = 15 and y is 7 then by substitution of 7 into the equation x must equal 8
In mathematics substitution is when one term in an equation is replaced by another that has a known value. This is so that the equation itself can be resolved.

Mathematics is not mean. It is the purest form of knowledge!
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
If you mean: -x+3y = 6 and x+3y = 18 then by substitution x = 6 and y = 4
If you mean: 2x+7y = -1 and 4x-3y = -19 then by substitution x = -4 and y = 1
