Question

Simplify 3(x-y) +4x- y & find their values for
(a) x = 2, y =0
(b) x = -2, y -1

Answer 1

Answer:

The answer is 14 & - 10

Step-by-step explanation:

a . For x =2 , y = 0

=3[(2) - (0)] + 4 (2) - (0)

=3 X 2 + 8

=6+8

=14

b. For x = -2 , y= -1

=3[(-2) -(-1)] + 4(-2) -(-1)

=3[ -2+1 ] + (-8) +1

=3X - 1 + (-7)

= -3 -7

= - 10
