Question

solve the system of linear equations graphically : 3x-5y=19,3y-7x+1=0​

Answer 1

Answer:

3x-5y=19

5y = 3x - 19

y = (3x - 19)/5 ............. (1)

3y - 7x + 1 = 0

3y = 7x - 1

y = (7x - 1)/3   .........(2)

Drawing these two graph in a graph sheet, they both intersect at (-2, -5)

The solution of the system of equations is x = -2 and y = -5
