Answer:

Not necessarily. There are many ways to write a basic equation with a negative answer. For example, -3-4 = -7. Here 4 is a positive number but because you subtract 4 to 3 or take away 4 from 3 being a negative number and so you get a negative answer. Another example is 6+(-9). There are a couple of ways you can resolve this. My method is to subtract 9 from 6 which gives you 3 and simply add a negative sign.

Let me know if you'd  like more examples. Hope this helps!! Sorry if it is confusing I can explain you in a more simpler way if you'd like.

Step-by-step explanation:

Question 3<br> Solve this system by using the elimination method.<br> 4x + 2y = 8<br> 5x + 3y = 9
umka21 [38]

Answer:

x=3, y=-2. (3, -2).

Step-by-step explanation:

4x+2y=8

5x+3y=9

---------------

simplify 4x+2y=8 into 2x+y=4

-----------------

2x+y=4

5x+3y=9

----------------

y=4-2x

5x+3(4-2x)=9

5x+12-6x=9

-x=9-12

-x=-3

x=3

2(3)+y=4

6+y=4

y=4-6

y=-2

What does J equal????????????????????????????<br> 3 + j / 11 =2<br><br> j =
AfilCa [17]


Let's solve the equation step-by-step

Step 1) Simplify both sides of the equation

3+ j/11 = 2

1/11j+3=2

Step 2) Subtract 3 from both sides

1/11j + 3 - 3 = 2 - 3

1/11j = -1

Step 3) Multiply both sides by 11

11 x (1/11j) = (11) x (-1)

j = -11

Answer is..  J = -11
