4x - 2y = 12

x + 2y = 8

(to cancel 2y, solve by adding)

4x - 2y = 12

+

x + 2y = 8

4x + x = 5x

-2y + 2y = 0

12 + 8 = 20

5x = 20

÷5

x = 4

Substitute x=4 to one of the equation:

x + 2y = 8

4 + 2y =8

-4

2y. = 4

÷2

y. = 2

Check:

4 + (2x2) does give you 8

Hope this helps!

I need help with both questions...
NikAS [45]

Answer:

17. a)

Step-by-step explanation:

17.

f(x) =x/2, then f(x-3)=(x-3)/2

x=3, f(x-3)=f(3-3)=f(0)=0 (values in table)

f(x-3)+3=0+3=3

18.

f(x) =x/2

f(x-2) for x=5 is f(5-2)=f(3)=3/2

f(x-2)+5=f(3)+5=3/2+5=3/2+10/2=13/2
