Answer:

x=13 and y =6

Step-by-step explanation:

y=x-7

y=6

Substitute y=6 into the first equation

6 = x-7

Add 7 to each side

6+7= x-7+7

13 = x

x=13 and y =6

Answer & Explanation :

1. x-7=6 Find x

2. Add 7 to both sides to make x alone.

3. x=13

4. Find y

5. y=6

6. Check your work:
Plug in the value of x to this equation, y=x-7

X=13 so y=13-7
This means that y=6 and x=13
