Example problems for easy algebra solver:
Some example problems are solved with solution for easy algebra solver.
Example 1:
Determine the x intercept of the equation.
4x - 7y = 12
Solution:
Given the equation
4x - 7y = 12
To find the x intercept we set y = 0 and solve for x.
4x - 0 = 12
Solve for x.
x = 12 / 4
x = 3
The x intercept is at the point (3, 0).
Example 2:
Evaluate f (3) - f (2)
f(x) = 6x + 3
Solution:
Given the function
f(x) = 6x + 3
f (3) - f (2) is given by.
f(3) = (6(3) + 3) = 18 + 3 = 21
f(2) = (6(2) + 3) = 12 + 3 = 15
f (3) - f(2) = (21) - (15) = 6
Solution to the given function is f(3) - f(2) = 6
Example 3:
Find the slope of the line or gradient passing through the points
(-5, -5) and (7, 7).
Solution:
Given the points (-5, -5) and (7, 7), the slope m is given by
m = (y2 - y1) / (x2 - x1)
= (7 – (-5)) / (7 – (-5))
= 12 / 12
= 1
m = 1
Solution to the given slope of the line m = 1.
Example 4:
Find the slope of the line
12x - 8y = 18
Solution:
Given slope of the line
12x - 8y = 18
Write the above equation in the form of slope intercept y = mx + b and identify the value of m the slope.
-8y = -12x + 18 both side can be divided by -8
-8y/-8 = -12x/-8 + 18/-8
y = 3/4x - 9/4
The slope is given by the coefficient of x which is 3/ 4.
Slope = 3/ 4
Example 5:
Solve x for the following linear equation 7x - 3 = 144
Solution:
Add by 3 on both sides, we get
7x - 3 + 3 = 144 + 3
Simplify both sides:
7x = 147
Divided by both sides on 7:
7x/7 = 147/7
Simplify both sides:
x = 21.
Solution to the linear equation is x = 21.
