Question

linear equation solver the following equation 3 \X-2 - 2 \x - 3 = 4 \ x - 3 - 3 \x - 1 \
​

Answer 1

Step-by-step explanation:

Example 1 Determine if the value 3 is a solution of the equation

4x - 2 = 3x + 1

Solution We substitute the value 3 for x in the equation and see if the left-hand member equals the right-hand member.

4(3) - 2 = 3(3) + 1

12 - 2 = 9 + 1

10 = 10

Ans. 3 is a solution.

The first-degree equations that we consider in this chapter have at most one solution. The solutions to many such equations can be determined by inspection.
