Question

What is the value of x in the equation below?
3/4x + 5 - 2x = 15

Answer 1

The value of x is 1.252762968495368

Solution:

Given that,

We have to find the value of x in given equation

Given equation is:

Simplify the left side of equation

Move 2 from left side to right side of equation

Therefore,

Taking ln on both sides

ln and e cancel each other each other

Therefore,

x = 1.252762968495368

Thus the value of x is found

Answer 2

`(3)/(4) x + 5 - 2x = 15 \\ (3)/(4) x - 2x = 15 - 5 \\ (3)/(4) x - 2x = 10 \\ 3x - 2x = 10 * 4 \\ x = 40`
