How many solution does 6-3x=4-x-3-2x

Step-by-step Simplifying

6 + -3x = 4 + -1x + -3 + -2x

Reorder the terms:

6 + -3x = 4 + -3 + -1x + -2x

Combine like terms: 4 + -3 = 1

6 + -3x = 1 + -1x + -2x

Combine like terms: -1x + -2x = -3x

6 + -3x = 1 + -3x

Add '3x' to each side of the equation.

6 + -3x + 3x = 1 + -3x + 3x

Combine like terms: -3x + 3x = 0

6 + 0 = 1 + -3x + 3x

6 = 1 + -3x + 3x

Combine like terms: -3x + 3x = 0

6 = 1 + 0

6 = 1

Solving

6 = 1

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
