Question 3

Make sure you read the directions for each part carefully. This system of equations will be used in all three parts of this question.
2x+3y=6
x-2y=10

Part 1: Solve the system by graphing. Draw the graphs on paper and indicate their intersection point. Type the ordered pair solution here as your answer to Part 1.

Part 2: Solve the system using the substitution method. Show all work here and indicate the solution for the system as an ordered pair.

Part 3: Solve the system using the addition method. Show all work here and indicate the solution for the system as an ordered pair

Answer 1

Part1: just identify 2 points for each equation (line) & look for point of intersection;
Part3: re-write it as:
2x+3y=6
-2x+4y=-20 (multiplied 2nd eq by (-2))
add together - x will cancel out, solve it for y, then - >x
Part2:
from the equation: x-2y=10
x=2y+10
put the value of x in second equation & solve it for y; then - >x

Answer 2

answers should be all the same:
x=6, y=-2
