    A set of equations is given below: Equation E: a = 5b + 1 Equation F: a = 3b + 4 Which statement describes a step that can be used to find the solution to the set of equations? Equation F can be written as 5b + 1 = 3b + 4. Equation F can be written as b + 1 = 3b + 4. Equation F can be written as a = 3(a − 1) + 4. Equation F can be written as a = 5(a − 4) + 1.

    A student is trying to solve the system of two equations given below: Equation P: y + z = 6 Equation Q: 8y + 7z = 1 Which of the following is a possible step used in eliminating the y-term? (y + z = 6) ⋅ −8 (y + z = 6) ⋅ 7 (8y + 7z = 1) ⋅ 7 (8y + 7z = 1) ⋅ 8

    To approach the first question: if y = 6x – 3 and y = 3x + 4 I can say that 6x – 3 = 3x + 4. Does that make sense?

    Substitute what a equals in the first equation for a in the second equation, that is your answer

    For the second, they want you to use the technique of adding together the two equations to have one variable cancel out. If you multiply the first equation by (-8), then you will have -8y in the first equation and +8y in the second equation. Adding the two equations together eliminates the Y variable , (-8y+8y) = 0y
