5.5x+21-x=50-4.5x-11
9x=50-32=18
x=2
How to calculate 2x = 5x
2x=5x
5x-2x=0
3x=0
x=0÷3
x=0
Calculation - 2x ^ 3 + 5x ^ 3
-2x^3+5x^3
=(-2+5)x³
=3x³
How to calculate 2x = 5x-2?
Forget it
The original formula is: 3x = 2
x=2/3
2 (5x × 2x + 5 × 5x + 2x × 5) = 40,
2(5x×2x+5×5x+2x×5)=40
10x^2+25x+10x=20
2x^2+7x-4=0
(2x-1)(x+4)=0
X = 1 / 2 or x = - 4
What is 5x greater than 2x
5x>2x
It holds when x > 0
18X+5X=4.6
18X+5X=4.6
Then 23x = 4.6
Then x = 4.6 △ 23
So x = 0.2
How to solve the equation of 15x + 3.8 = 9x + 11.3
15X-9x=11.3-3.8
6X=7.5
X=1.25
How to solve the equation of 0.9x-80 = 0.75x + 70?
0.9X-80=0.75X+70
0.9x-0.75x=70+80
0.15x=150
x=1000
Equation 9x 8.8
Equation 9x + 8.8/22 = 4.5,
9x+8.8/22=4.5
9x+0.4=4.5
9x=4.1
x=4.1/9
x=41/90
