How to solve 50x + 100 * 3 / 5x = 1100

50x+100*3/5x=1100 50x+60x=1100 110x=1100 x=1100÷110 x=10

[solving equations (4 in total)] (1) 1 / 2 (5-5x) ^ 2 = 50x (x + 1) ^ 2 (2) x ^ 2-6x-2 = 0
（1）1/2(5-5x)^2=50x(x+1)^2
（2）x^2-6x-2=0
(3) X ^ 2 - (root 3 + root 2) x + root 6 = 0
（4）x^2-4=2(2x-x^2)+3

(1) Equation 1 / 2 (5-5x) ^ 2 = 50x (x + 1) ^ 2 can be reduced to: 25 (1-x) &# 178; = 100 (x + 1) &# 178; that is, (1-x) &# 178; = 4 (x + 1) &# 178; the above formula is equivalent to: 1-x = 2 (x + 1) or 1-x = - 2 (x + 1), that is: 3x = - 1 or x = - 3, the solution is: x = - 1 / 3 or x = - 3 (2) equation x ^ 2-6x-2 = 0, the formula is: (x-3) &# 178

Equation: 90x = 72%, 49x - 34x = 30x + 18 = 2.28x - 75X = 16

Hello: 90x = 72 x = 72 △ 90% x = 80% 49x - 34x = 3015% x = 30x = 30 △ 15% x = 200 x + 18 = 2.28 x = 2.28-0.18x = 2.1X - 75X = 1625% x = 16x = 16 △ 25% x = 64 If you don't understand this question, please click "adopt as satisfied

Solving equation 75x-14.5 * 3 = 0

75x-14.5 * 3 = 0
0.75x-43.5=0
0.75x=43.5
x=43.5/0.75
x=58

{1} 18x-1.5x = 82.5 {2} 8.5x-x = 38.5 (3) 0.75x + 81.5x = 3294, all of which need to be listed in detail

{1}18x-1.5x=82.5
x(18-1.5)=82.5
16.5x=82.5
x=5
{2}8.5x-x=38.5
x(8.5-1)=38.5
7.5x=38.5
x=5
(3)0.75x+81.5x=3294
x(0.75+81.5)=3294
82.25x=3294
x≈40

How to solve 50x + 40x × (2.5x) = 120?
We need to explain it in detail

50X+40X×(2.5X)=120
50X+100X=120
150X=120
X=120/150
X=0.8

Equation 50x △ 2 = 120

50x÷2=120
50x=240
x=24/5 =4.8

(120-50x) / 5 = (50x-5x) / (50 + 5) + (120-50x) / 50

(120-50x)/5=(50x-5x)/(50+5)+(120-50x)/50
24-10x=9x/11+(12-5x)/5
Take 55 on both sides
1320-550x=45x+132-55x
450x=1188
x=66/25
