Which steps should be taken to solve the equation 2x+3=x+5?

x = 2

Step-by-step explanation: 2x+3=x+5

Step 1: Subtract x from both sides.

2x+3−x=x+5−x

x+3=5

Step 2: Subtract 3 from both sides.

x+3−3=5−3

x=2

x=2

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

its 8
