Answer 1

Answer:

I gonna make it a la la la la la la la la la la la la la la la la alone

Answer 2

Answer:

Step-by-step explanation:

3x+5y = 9 (1)

5x+3y = 7 (2)

Adding the two equations

8x+8y = 16

x+y = 2 ( dividing by 8) ( equation 3)

Subtracting the equation (1) from equation (2)

2x-2y= 2

x-y = 1 (dividing by 2) equation (4)

Adding equation (3) & (4)

2x= 3

x= 3/2

Substituting the value of x in equation (3)

x+y = 2

3/2+ y = 2

y= 2–3/2

y= (4–3)÷2

y= 1/2

x= 3/2 & y = 1/2
