Question

Evaluate each expression, given x = 2 and y = 3.
Ex. 2x + 4y = 2(2) + 4(3) = 4 + 12 = 16
1. 12y + 3x =

2, 5x + 2y =

3. 8x - 2y =

4.7x - 4y + 6xy=

5. 2x + y =

a.7
b.38
c.10
d.60
e.33

please answer all (math)​

Answer 1

Answer:

12y+3x=12(3)+3(2)

=36+6

12y+3x=42

5x+2y=5(2)+2(3)

=10+6

5x+2y=16

8x-2y=8(2)-2(3)

=16-6

8x-2y=10

7x-4y+6xy=7(2)-4(3)+6(2)(3)

=14-12+36

7x-4y+6xy=38

2x+y=2(2)+3

=4+3

2x+y=7

Hope this helps you
