Solution equation: 4.5X + 3.8x = 16.6 5 / 6 + 1 / 3 = 7 / 20, 1 / 2: x = 3 / 5, 1-30% x = 0.5

Solution equation: 4.5X + 3.8x = 16.6 5 / 6 + 1 / 3 = 7 / 20, 1 / 2: x = 3 / 5, 1-30% x = 0.5

4.5x+3.8x=16.6
8.3x=16.6
x=2
5x of 6 + 1 of 3 = 7 of 20
5x/6=7/20-1/3
5x/6=1/60
x=1/50
1 / 2: x = 3 / 5
x=1/2÷3/5
x=5/6
1-30%x=0.5
0.3x=0.5
x=5/3

Solution equation: 4.5X + 5.8x = 16.60.5: x = 3:0.8
Write the score with endless division

x=166/103
x=2/15

X-8 X-9 = 0
How do you calculate this? I forgot about high school

x²-8x-9=0
The factorization results in (X-9) (x + 1) = 0
Solution
X = 9 or x = - 1

X + 16-8x = 1

X + 16-8x = 1
x^2-8x+15=0
(x-3)(x-5)=0
x=3 x=5
