Determine the equivalent system for the given system of equations:

5x + 3y = 1
4x − 5y = 4

a. 5x + 3y = 1
8x − 10y = 4

b. 5x + 3y = 1
9x − 2y = 5

c. −5x − 3y = 1
4x − 5y = 4

d. 2x + 3y = 7
9x − 2y = 4

B

Step-by-step explanation:

5x + 3y = 1 25x + 15y = 5

4x - 5y = 4 12x - 15y = 12

37x = 17          x = 17/37

y = (1- 5 x (17/37)) /3 = - 16/37

B. 5x + 3y = 1     5 x 17/37 + 3 x (- 16/37) = 37/37 =1

   9x - 2y = 5    9 x 17/37 - 2 x (- 16/37) = 185/37 = 5

5x + 3y = 1  

9x − 2y = 5
