If the equation is 3(x+1)=12+4(x-1) then the value of x is -5.
Given that the equation is 3(x+1)=12+4(x-1).
We are required to find the value of variable x that is present in thee equation.
Equation is basically a relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation, cubic equation and many more depending on the power of the variables present in it.
The equation is 3(x+1)=12+4(x-1).
To find the value of variable x we need to solve the equation.
3x+3=12+4x-4
3x-4x=12-4-3
-x=5
x=-5
Hence if the equation is 3(x+1)=12+4(x-1) then the value of x is -5.
