4x-25=-3y,3x+3y=40 pleased with all the

Answer 1

Answer:

x = - 15 and y = 85/3

Step-by-step explanation:

4x + 3y = 25 ...(i)

3x + 3y = 40 ...(ii)

Subtracting both the equations we get:

(4x + 3y) - (3x + 3y) = 25 - 40

4x + 3y - 3x - 3y = - 15

x = - 15

Putting the value of x in equation (i)

4(- 15) + 3y = 25

- 60 + 3y = 25

3y = 25 + 60

3y = 85

y = 85/3
