Solve the systems of equations below using the method of your choice. Check your solutions, if possible. Homework Help ✎
The Substitution Method can be used to solve both of these systems.
Substitute '7 − 2x' for y in '2x + y = 10.'
2x + (7 − 2x) = 10
Solve for x. What do you notice about this system?
7 ≠ 10
Follow the steps in part (a), but substitute
'3y − 1' for x in '4x − 2y = 10.'
