If it's 927 divided by 3 the answer is 309
<u>1 + 4x = -5 + 7x</u>
1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:
1+5=7x-4x
2nd step:
3x=6
3rd step: you need to divide both sides into 3, because it is the common divisor.
x=2
<h2>
To sum up:</h2>
<em>1 + 4x = -5+7x</em>
<em>7x - 4x = 1 + 5</em>
<em>3x = 6</em>
<h2>
<em>x = 2</em></h2>
You can try to memorize the summary. However, it is better to understand the solution as a whole.

Answer:
Step-by-step explanation:
Given:
Volume of water in p = 65 gallons
Volume of water in q = 63.5 gallons
Initially,
Vip = 65 gallon
Viq = 63.5 gallon
Volumetric rate, v = volume/time
At the time both tanks will be filled,
Vfp = Vfq
Final volume, Vf = Vi + v×t
65 - vt = 63.5 + vt
65 - Kt = 63.5 + Mt
Calculating t,
65 - 63.5 = Mt + Kt
1.5 = (M + K) × t
Time, t = 1.5/(M + K) minutes
