Solve for x in first equation:
x-2y=7
Add “2y” to both sides
x=2y+7
Put this in to second equation:
3(2y+7)+2y=21
Solve for y:
Distribute the 3 into the ()
6y+21+2y=21
Combine the like y terms
8y+21=21
Subtract 21 from both sides
8y=0
Divide by 8 on both sides
y=0
Put this into the first solved equation:
x=2(0)+7
Solve for x:
Multiple 2(0)
x=0+7
Add 0 and 7
x=7
So the value of x is positive 7.
All you have to do is subtract the amount of nails, from the amount of bolts.
The answer would be:
4,966,464
I hope this Helps :)
6. you plug in -2 for x. -(-2) makes a positive 2 so the equation ends up being 2+ 4 =6
Answer:

Step-by-step explanation:
Answer:
The length of W'X' will be exactly given by, 12 unit.
Step-by-step explanation:
Rectangle WXYZ is dialated by a factor of 
to form the rectangle W'X'Y'Z'.
So, if the length of WX is 5 unit, the length of W'X' will be exactly given by,
lenght of WX 
Dialation factor
= 
unit
= 12 unit
