The solution set of the inequality -8 ≤ 3x + 7 ≤ 10 is [-5, 1]
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Given the equation:
a + b = 2c
making b the subject:
b = 2c - a
Also if 2x - 5y = 8:
x = 4 + (5/2)y
The value of b in the equation a + b = 2c is b = 2c - a. Also, 2x - 5y = 8 is equivalent to x = 4 + (5/2)y
