Answer:
(2, 3).
Step-by-step explanation:
3x+2y=12
6x+3y=21 Multiply the first equation by 3 and the second by 2:
9x + 6y = 36
12x + 6y = 42 Subtract:
-3x = -6
x = -6/-3 = 2.
Plug x = 2 into the first equation:
3(2) + 2y = 12
2y = 12 - 3(2)
2y = 6
y = 3.
Answer:
if you divided 200 by 5.50 the answer will be 36.3636363636
Answer:
There is no picture.
Step-by-step explanation:
<span>Simplifying
y = 20x + 500
Reorder the terms:
y = 500 + 20x
Solving
y = 500 + 20x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 500 + 20x</span>
Answer:
5
Step-by-step explanation:
To solve a problem with negatives, we use the following rule.
If it is like
x+(-y), it is equivalent to x-y
If the equation is like
(-x)-(-y), it is equivalent to (-x)+y
So,
5+(-11)=5-11=-6
(-6)-(-11)=(-6)+11=5
Your answer is 5.
