What are a definition and an example of a linear equation?
- An equation with only one variable is referred to as a linear equation in one variable.
- It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value.
- A linear equation in one variable would be 9x + 78 = 18, for instance.
total trip time = 5 hr
speed when drove to a friends house = 45 mph
speed when drove back = 30 mph
x/45 + x/30 = 5
45x + 30x = 5 * 45 * 30
75x = 6750
x = 6750/75
x = 1350
Total distance travel by michael is 2 x = 2 × 1350 = 4050 miles
