You do the sum backwards,
36-16=17
17x3=51
Then you check it to make sure,
51/3=17
17+19=36

Eugene can buy 19 oranges because 146.11 divided by 7.69 is 19
Answer:
the correct structure would be B
Answer:
Linear equations have a reduced form of
m*x + b = 0
Answer:
x = -2 and y = 0
Step-by-step explanation:
5x + y = -10
4x - 7y = -8
Rearrange the first equation to equal y.
5x + y = -10
y = -10 - 5x
Replace y in the second equation with the first equation.
4x - 7y = -8
4x - 7(-10 - 5x) = -8
4x - (-70 -35x) = -8
4x + 70 + 35x = -8
Rearrange the equation to find x.
4x + 35x = -8 - 70
39x = -78
x = -2
Now that you know x, use the rearranged first equation to find y.
y = -10 - 5x
y = -10 - 5(-2)
y = -10 + 10
y = 0
