Solve the equation 0.7-0.1 X / 0.5-x-1 / 3 = X-2 / 6 0.7-0.1x x-1 x-2 ———— - ———— = ———— 0.5 3 6 In the middle is the fractional line
(0.7-0.1x)×2-(x-1)÷3=(x-2)÷6
1/3+1.4×6-3=4.2x
5.41/3=4.2x
5.4+1/3
x=————

x=1.351/3
The square of x minus 5 / 16 of x = 0
With the formula method solution! Thank you
x²-x-5/16=0
(x-1/2)²-1/16=0
x-1/2=1/4
x=3/4

Solve an equation 32x + 41 * (1 / 2-x) = 17.8
32x+41*(1/2-x)=17.8
32x+41*1/2-41x=17.8
32x+20.5-41x=17.8
41x-32x=20.5-17.8
9x=2.7
x=2.7÷9
x=0.3
Excuse me: 8 (x-6.2) = 41
Solution
8(x-6.2)=41.6
8x-49.6=41.6
8x=91.2
x=11.4
Solving the equation; detailed steps with 24 / X equal to 2 / 3
24 / x = 2 / 3, that is, 2x = 24 * 3, x = 36
Solution equation: 17 / 6 (x24) = 3 (x-24)
17/6(X24)=3(x-24)
17 (x + 24) = 18 (x-24) [multiply both sides by 6]
x=17×24+18×24
x=840
Solve the equation. 50% x + 30% x = 8 x-40% x = 90 4x + 3 × 0.7 = 6.5
(1)50%x+30%x=8, (50%+30%)x=8, 0.8x=8, 0.8x÷0.8=8÷0.8, x=10;(2)x-40%x=90, (1-40%)x=90, 0.6x=90, 0.6x÷0.6=90÷0.6, x=150;(3)4x+3×0.7=6.5, 4x+2.1=6.5, 4x+2.1-2.1=6.5-2.1, 4x=4.4, 4x÷4=4.4÷4, x=1.1.
The solution equation: 8y-3 = 5Y + 3,2 (x + 3) = 3 (2x-1) + 5,3 (x-3) + 4 = 2x-2,5 (x + 8) - 5 = 6 (2x-7), 7 (- 2x + 3) - 3 = 2 (x-3) + X
Also, 4x-8 = 2 (- 3-2x)
8y-3=5y+3,
8y-5y=3+3
3y=6

120 / 4 = 600-x / 16 (solving equation)
120/4=600/16-X
30=37.5-X
X=37.5-30
X=7.5
