Answer:
His profit is 105 rs
Step-by-step explanation:
if he bought 7 books for 525 RS,that means 1 book costs 75 rs
if he sold 4 books for 360 RS,that means 1 boo costs 90 RS
90×7=630.
630-525=105
T=5
divide both sides by numeric factor on left side then solve
To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
The given equation is

.
Let's perform step 1: reducing one side to variables only. By adding

to both sides of the equation, we get

.
Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of

is

, we need to divide both sides of the equation by 4:

. Rounded to the nearest tenth,

.
So the value of

that satisfies

is

.
