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?
Group of answer choices
1. Solve the first equation for y in terms of x: y = 4x - 3
2. Substitute the expression for y in the second equation: 2x + 7(4x - 3) = 41
3. Simplify the equation and solve for x.
