True
 * Answer**

__**Example:**__

when x = 4 substituting for x gives you
 * y=3x-5**

3*4 = 12 12-5 = 7   Solution for y = 7 y is another variable.

When you substitute x for 4 it allows you to solve for y This can go for any expression when you use substitution it allows you to solve for the other variable which is the reason why the answer is true. 15. True, you could substitute the variable w/ any number that would add up to the sum/ product/etc. 2*w=16 2+w=10 16/2=w=8 10-2=w=8 edited by Natalie Sanchez
