The solution for the given equation 3x+1 = 4 is x=1.
<u>Step-by-step explanation:</u>
The equation to be solved is given as 3x+1 =4.
<u>The steps to be followed are :</u>
To solve this equation and to find the x value, bring x alone on one side to get a value for x.
For this, the first step is to subtract 1 from both sides of the equation. You get, ⇒ 3x+1-1 = 4-1
⇒ 3x = 3.
The next step is to divide 3 on both sides of the equation.
⇒ 3x/3 = 3/3
⇒ x = 1
Therefore, the above steps must be followed in order to solve the equation 3x+1 = 4. The solution is x=1.
Did they complete half of the trip? I think a word is missing!
It would cost 26 dollars because 3 multiplied by 8 is 24 plus 2/3 of 3 is 26 and that is the result of 2/3 of 3 being 2 dollars

Question:</h2>
Evaluate using a suitable identity: (997)³
<h2>
Answer:</h2>
991026973
<h2>
Step-by-step explanation:</h2>
Given:
(997)³
To solve this using an appropriate identity;
i. <em>Rewrite by splitting the value in bracket (997) into a difference of two numbers. i.e</em>
(997)³ = (1000 - 3)³
<em>ii. Use the appropriate identity</em>
Since the split from (i) above gave a cube of the difference of two numbers, we can apply the following identity for finding the cube of the difference of two numbers;
(a - b)³ = a³ - b³ - 3ab(a - b)
In this case;
a = 1000
b = 3
<em>(iii) Substitute the values of a and b into the identity equation and solve;</em>
(1000 - 3)³ = 1000³ - 3³ - 3(1000)(3)(1000 - 3)
(1000 - 3)³ = 1000000000 - 27 - 9000(997)
(1000 - 3)³ = 1000000000 - 27 - 8973000
(1000 - 3)³ = 991026973
Therefore,
(997)³ = 991026973
