Assignment:
Solve each system by the substitution method only.
Q1) 4x + 3y + 15
2x – 5y = 1
Q2) 3x – 7y = 13
6x + 5y =7
Q3) 3x – 4y = 11
2x + 3y = -4
Q4) 2x + 3y = -16
5x – 10y = 30
Q5) 3x = 4y + 1
3y = 1 – 4x
Q6) 5x = 6y + 40
2y = 8 – 3x
Provide complete and step by step solution for the question and show calculations and use formulas.
