Question

⁴⁄₃ ( 2x + 1 ) + 7 ≤ 3 + ⁵⁄₂ ( x + 2 ) , x ∈ Q
Find Solution set of the above equation.

Answer 1

Answer:

Answer:

Linear equations are equations of the first order. These equations are defined for lines in the coordinate system. An equation for a straight line is called a linear equation. The general representation of the straight-line equation is y=mx+b, where m is the slope of the line and b is the y-intercept.

Answer 2

Answer:

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.
