Question 1076566: A system of equations is given below:
y = 4x − 3
2x + 7y = 41
Which of the following steps could be used to solve by substitution?
2(y = 4x − 3) + 7y = 41
4x − 3 = 2x + 7y
2x + 7(4x − 3) = 41
2(y = 4x − 3) Answer by math_helper(2461) (Show Source):
You can put this solution on YOUR website! 2x + 7(4x − 3) = 41
"(4x-3)" (from the first equation) is clearly substituted for "y" in the 2nd equation. I hope you see this and understand it. If not, find some problems that you can solve for practice.
