Question

Can you please help me please ​

Answer 1

(4 , -3)

Explanation:

Put "y" by itself on one side to isolate it

3x - y = 15

3x = 15 + y

3x - 15 = y

Substitute "y" in the second equation for "3x - 15"

x + (3x - 15) = 1

4x - 15 = 1

4x = 16

x = 4

Then, plug 4 into x in any of the equations

4 + y = 1

y = -3

(4 , -3)
