Answer: 8 + x = 3
To solve for this, we need to get x by itself on one side of the equation.
Currently, we have 8 being added to x, so we need to perform the opposite order of equations to get rid of 8.
The opposite of +8 is -8, so subtract 8.
Remember, if you add, subract, multiply or divide by any new number, you must do it to both sides of the equation.
8 + x = 3
Subtract 8 from both sides.
8 - 8 = 0
3 - 8 = -5
We're now left with:
x = -5
Your answer is A.) -5.
I hope this helps! can u pls give me brainliest
Step-by-step explanation:
Answer:
multiply the first equation by -2, then add them
Step-by-step explanation:
7x+4y=-4 *-2 7x+4y=-4 *-2 = -14x-8y=8
5x+8y=28
-14x-8y=8 x=-4, y=6
-9x=36
x=-4
7(-4)+4y=-4
-28+4y=-4
4y=24
y=6
Answer:
x=2
Step-by-step explanation:
3(5x+2)=8x+20
Distribute the 3
15x +6 = 8x+20
Subtract 8x from each side
15x-8x +6 = 8x-8x+20
7x+6 = 20
Subtract 6 from each side
7x+6-6=20-6
7x=14
Divide each side by 7
7x/7 = 14/7
x=2
There should be an X over 9.6, 0, √16, and 2.45.
9.6 = Integer
0 = Whole Number
√16 (or 4) = Counting Numbers
2.45 = Integer
