Solve for x: 3(x + 1) = -2(x - 1) - 4.
Solution:
A linear equation is a type of equation in which the degree of each variable in the equation is exactly equal to one.
Linear equations in one variable are those equations in which there is only one variable present, and there is only one solution of the equation.
The general form of a linear equation in one variable is Ax + B = 0.
Here A is the coefficient of x, x is the variable, and B is the constant term.
Given, 3(x + 1) = -2(x - 1) - 4
We have to solve for x.
3x + 3 = -2x + 2 - 4
3x + 3 = - 2x - 2
3x + 2x = -2 - 3
5x = -5
x = -5/5
x = -1
Therefore, the value of x is -1.
Solve for x: 3(x + 1) = -2(x - 1) - 4.
Summary:
The solution of x in 3(x + 1) = -2(x - 1) -4 is -1. Linear equations in one variable are those equations in which there is only one variable present, and there is only one solution of the equation.
