The number will be -1
Linear equation
- A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept
- Linear equation is an equation between two variables that gives a straight line when plotted on a graph.
- Linear equations are a combination of constants and variables.
How to solve the problem?
The steps are as follow:
- Assume ‘X’ will be the given number. Now perform the operations
- Adding 7 to a number: x + 7
- After that subtracting 4 from double the number:
x + 7 = 4 - 2x
x + 2x = 4 - 7
3x = -3
x = -1
So, the number will be -1
