the answer is 15 loads of gravel because 3 times 2 equals 6 which means 3 * 5 is equal to 15
x= 9
y= 9
4x -2y= 18.................equation 1
-4x + 2y= -18...............equation 2
From equation 1
4x= 18 + 2y
x= 18 + 2y/4
substitute 18+2y/4 for x in equation 2
-4(18+2y/4) -2y= 18
-(18+2y)-2y= 18
-18-2y-2y= 18
-18+4y= 18
4y= 18+18
4y= 36
y= 36/4
y= 9
Substitute 9 for y in equation 1
4x-2y= 18
4x-2(9)= 18
4x-18= 18
4x= 18+18
4x= 36
x= 36/4
x= 9
Hence the value of x is 9 and the value of y is 9

Answer:
See below.
Step-by-step explanation:
It is the one at the top left side.
The line y = x passes through the origin at an angle of 45 degrees to the x axis and rises to the right.
So if you imagine its a mirror you'll see that its a reflection in that mirror.
14 = 2•7 and 35 = 5•7, so the GCF of 14k and 35 is 7.
14k + 35 = 2•7k + 5•7 = 7 (2k + 5)
(Remember that the distributive property says a (b + c) = ab + ac.)
