When solving a system by substitution, one should:

• look for coefficients that are reciprocals

• solve for x or y in one equation first

• look for coefficients that are the same or opposites

• always multiply by -1

Is the given point a solution to the system.

3x - y = 4

7x+2y = -5

• yes

• no

Solve the system by SUBSTITUTION. 4x – 3y = 6 y = 2
