Step-by-step explanation:
Solve by elimination.
multiply the lower equation by negative 1.
-y=7x-21
-y+y=o
new equation is
7x+6-52=0
6-52 is -46
-7x=-46
divide by -7
x=6.57...
plug it back in
y= 7(6.57)+21
7*6.57= 46
y=46+21
y=67
(might be wrong, I tried)
6 + 0 = 6 is the zero property of addition which states that a number does not change when adding/subtracting zero from the number
So, to start off, find the total amount of words that there must be.
