Question

Solve the following linear equation :
5x - 5y - 4 = 0 and 9x = 2y + 7

Answer 1

Answer:

5x - 5y = 4 or x - y = 4/5--------equation 1

9x - 2y = 7 -------equation 2

Substituting value of x from equation 1 in equation 2

(36 +45y - 10y)/5 = 7

36 + 35y = 35

Therefore, y = -1/35

Therefore x = 27/35
