Answer: Twice a number decreased by two is equivalent to that number increased by five then the number is 7
Step-by-step explanation:
The equation for a linear equation in one variable is written as ax+b = 0, where a and b are two integers, and x is a variable. This equation has only one solution. For instance, the linear equation 2x+3=8 only has one variable. As a result, this equation has a single solution, x = 5/2. A linear equation with two variables, however, has two solutions.
Twice a number decreased by two is equivalent to that number increased by five. Let x = unknown number
2x - 2 = x + 5
x = 7
