Algebra I
Name __________________
6.3 B Worksheet
Objective: To solve Linear Systems of Equations by Combinations involving Rearranging.
Remember the goal: We need to get one of the variables with an _____________
_____________ as that same variable in the second equation!
Rearrange, Multiply, Combine:
Ex 1.
4x = -3 + y
y = -6x – 7
Ex 2.
3.
1. x = 2y + 9
2y = 3x - 19
4x = 5y + 6
2. 3y = 5x + 15
3y + 2x = -8
3x = y – 9
4x = -11 + y
4. x = 2y – 3
y = -6x – 9
2y = 3x + 13
5.
4y = 15 – 3x
2y = 3x + 21
7.
5x = 4y - 30
2x + 3y = -12
9.
4x = -11 + y
Y = -7x – 11
11.
2y = 1 – 3x
-3y = 1 + 4x
6. 4x = 5y – 14
3y – 8x = -14
8. 2y = 30 + 4x
15x = y + 24
10. x = 4y + 13
4y = 3x – 23
12. 8y = 7x + 32
6y = 24 – 5x
