Question

Solve 3x+2y=5 and x-y=-10 in substitute method.​

Answer 1

Answer:

-3 , 7

Step-by-step explanation:

3x+2y=5

x-y=-10 or x = y-10

substituting in 1st equation,

3(y-10) + 2y = 5

y = 7

x = -3

Answer 2

Answer:

x = -3 and y = 7

Step-by-step explanation:

Given, x - y = -10

=> x = -10+y

Now in 3x + 2y = 5, substituting the value of x

=> 3(-10+y) + 2y = 5

=> -30 + 3y + 2y = 5

=> 5y = 5 + 30

=> y = 35/5 = 7

and value of x = -10+y

= -10 + 7

=> x = -3
