Answer:
-6
Step-by-step explanation:
7x + 9 = 5x -3
-5x -5x
2x+9=-3
-9 -9
2x=-12
divide by 2
x = -6
Answer:
d=2,866
Step-by-step explanation:
7134+d=10000
Subtract 7,134 from both sides.
7134+d-7134 = 10,000 -7134
d=2866
Answer:
Hi there!
Your answer is:
x= 1
Step-by-step explanation:
Goal- get all X's on one side, and all whole numbers on the other
2+3x -x = 4x
First, combine like terms on each side of the equal sign
2+ 2x = 4x
Next, think about the additive inverse property. What, added to 2x, equals 0? 2x + (-2x) =0! So, we <u>subtract</u> 2x from both sides!
2= 4x-2x
Simplify
2= 2x
Divide both sides by the coefficient of x (in this case, 2)
2/2 = x
2/2 is equal to 1
1= x
Hope this helps!
