whats 4x+3=2x+13?

4x + 3 = 2x + 13

Subtract 2x from both sides

4x - 2x + 3 = 13

2x + 3 = 13

Subtract 3 from both sides

2x = 13 - 3

2x = 10

Divide both sides by 2

x = 10/2

x = 5



90 km/h = m/min

90 km/h =

90 x 1000 m
------------------
60

90 km/h = 1500 m/min

4x - 2x = 13 - 3
2x = 10
x = 5

4x + 3 = 2x + 13
2x = 10
x = 5

Answer: x = 5

Proof (1st equation):
4(5) + 3 = 2(5) + 13
20 + 3 = 10 + 13
23 = 23

whenever you have to find x in similar questions, all you have to do is moving the x factors to one side and the whole known numbers to the other side of the equal sign by changing the sign of the numbers you move:

4x +3 = 2x+13 becomes 4x - 2x = 13 - 3
=> 2x = 10 => x = 10/2 = 5

Hope this will help you in other equations.

For the "4x+3=2X+13" question, you need to get your variable alone. To do that, subtract 3 from both sides, which results in "4x=2x+10". Next, you need to put your variables together, so subtract 2x from both sides, which is "2x=10", then simply divide both sides by 2 and "x=5".

4x+3=2x+13
=4x-2x=13-3
=2x=10
=x=10/2
=x=5

1km=1000 m
1 hour=60 minutes

so....
90 km/h= 90 * 1000/60
=9000/6
=1500m/min

4x + 3 = 2x + 13
4x - 2x = 13 - 3
2x = 10
x = 5

90km/h = ? m/s
(90 * 1000) / 60 = 1500m / min

4x+3=2x+13
4x - 2x = 13 - 3
2x = 10
x = 5

90km/h= m/min
90km/h = (90/60)km/min
= (90/60)*1000 m /min
= 1500 m/min

1)
4x + 3 = 2x + 13
4x - 2x = -3 + 13
2x = 10
x = 10/2
x = 5

2)
90 km/h
= 90 x 1000/60
= 90000/60
= 1500 m/min (1.5 km/min)

4x-2x = 13-3
2x = 10
x=5


(90km/h) x (1000m / km) x (1 hr / 60 m) = 1500 m/ min
