The solution of the equation –3x + 1 + 10x = x + 4 will be 1/2. Then the correct option is A.
<h3>What is simplification?</h3>
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The equation is given below.
–3x + 1 + 10x = x + 4
On changing, we have
6x = 3
x = 1/2
Then the correct option is A.

Answer:
x = 400 when y = 100
Step-by-step explanation:
This is a question in relation to direct variation.
y ∝ 
y = k
Given that, y = 45, x = 81. Then;
45 = k 
45 = 9k
k = 
k = 5
Thus the relationship among the variables is;
y = 5
If y = 100, then;
100 = 5
= 
= 20
x = 
x = 400
Therefore, x = 400 when y = 100.
