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.
substitution
it means changing the mathematics information
The substitution method in mathematics is a technique used to solve systems of equations by isolating one variable and substituting it into the other equation. The method is not attributed to a single inventor, as it has been used by mathematicians for centuries. The concept of substitution in algebra can be traced back to ancient civilizations such as the Babylonians and Greeks, who used similar methods to solve mathematical problems.

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
