Answer:
D; y = x
Step-by-step explanation:
1. Slope-intercept form
The general formula of a line is;
y = mx + b
Where "m" is the slope, and "b" is the y-intercept.
2. Slope
The slope of a line is;
The slope of the given line is; . This is because the line goes up 4 units, and over to the right by 7 units.
3. Intercept
This line passes through the origin, meaning it has no y-intercept.
4. Putting it together
Substitute in the value found, into the general equation.
y - mx + b
m =
b = 0
Hence the equation of the line is;

1.4375
<u>Step-by-step explanation:</u>
Step 1:
Let the given equation be
To find X simplification of terms using BODMAS ( Brackets Orders Division Multiplication Addition Subtraction) is done as follows.
Step 2:
Let us expand the equation as
Step 3:
Let us expand it further as
Step 4:
To find X segregate X in one side and all other remaining terms in other side as follows
After the simplification the numerical value is
Step 5:
Keep X along one side and bring 48 to the denominator of another side to find X as follows
And the value of X is 1.4375
