Explanation:
Just Multiply :)
5x + y = 2
4x + y = 4
5x + y = 2
-(4x + y = 4)
5x + y = 2
-4x - y = -4
x = -2
x = -2
5x + y = 2
5(-2) + y = 2
-10 + y = 2
y = 2 + 10
y = 12
x = - 2
4x + y = 4
4(-2) + y = 4
-8 + y = 4
y = 4 + 8
y = 12
x = -2 ; y = 12 ⇒ (-2,12)
2abc - 3ab ║ 2 (2) (3) (4) - 3 (2) (3)
You would multiply and the products - you are going to subtract
2 × 2 × 3 × 4 = 48
3 × 2 × 3 = - 18
