Answer:
66
Step-by-step explanation:
<u>solve the problem backwards</u>:
?/3=?-7=15
The opposite of subtract is adding
15+7=22
The opposite of division is multiplication
(22)3=66
plug 66 in:
66/3=22
22-7=15
<u><em>Answer</em></u>
= 3.405 × 10⁻⁴
<u>Explanation</u>
If the question is correctly written, then it is very easy.
First, take the like terms on one side.
493x = 3432x+1
493x - 3432x = 1
-2939x = 1
Dividing both sides by -2939 to get the value of x.
x = 1/(-2939)
= - 0.0003405
= 3.405 × 10⁻⁴
6yzx5+30y^2z
if you just distribute it all out you get the answer
6yz(5y + 2z - 3)<span>

Answer:
x=−3.533333
Step-by-step explanation:
21
3
−1.5x=12.3
Step 1: Simplify both sides of the equation.
21
3
−1.5x=12.3
7+−1.5x=12.3
−1.5x+7=12.3
Step 2: Subtract 7 from both sides.
−1.5x+7−7=12.3−7
−1.5x=5.3
Step 3: Divide both sides by -1.5.
−1.5x
−1.5
=
5.3
−1.5
x=−3.533333
