Question

using substitution method solve the equation 3x+4y=10 and x-y=2. final answer x=2 and y=1.

Answer 1

Answer:

The key insight here is that for the second equation, we can easily solve for a variable in term of the other variable. Let's just add y to both sides to solve for x in terms of y . x=y+1. We can plug this value of x into the first equation in the system. Distributing the 3 to both terms in the parenthesis, we get.
