The solution equation is 26 × 0.5-4x = 7
(X-7) △ 3 = 8 16.5-4x = 14.59 2 × (x + 1) = 6

26×0.5－4x=7
-4x=7-13
-4x=-6
x=3/2
x=1.5
（x-7）÷3=8
x-7=24
x=31
16.5-4x=14.5
-4x=14.5-16.5
-4x=-2
x=0.5
2 / 9 × (x + 1) = 6
x+1=27
x=26

Solve the equation 4x + 12 = 50
2 out of 3 plus 1 out of 6 = 15
5 out of 7 divided by 5 out of 14 = 7 out of 8

4X+12=50
4x=50-12
4x=38
x=38÷4
x=9.25
2 out of 3 plus 1 out of 6 = 15 times 6
4x+1=90
4x=90-1
4x=89
x=89÷4
x=22.25
5 out of 7 divided by 5 out of 14 = 7 out of 8
2x=7/8
x=7/8÷2
x=7/16

Solving equation 1.1 (4x-1) = 12.1

1.1（4x-1）=12.1
4x-1=12.1÷1.1
4x-1=11
4x=11+1=12
x=12÷4
x=3

Solution equation: 4x-12 = x + 12

I wrote step by step. It's really handwritten
4x-12=x+12
4x-12-x+12=x+12-x+12
4x-x=12+12
3x=24
x=8

12 * 4-4x = 28

12*4-4x=28
48-4X=28
-4x=-20
X=5

2.4 × 2.5-4x = 2 solution equation

Solving the equation 4x ^ 2-4x + 1 = 5

4x^2-4x+1=5
（2x-1）^2=5
2x-1=±√5
2x=1±√5
x=1/2±√5/2

4X -- 3.7 = 8.7 (solving equation)

Negative results in positive, and 4x + 3.7 = 8.7
4x=8.7-3.7
4x=4
x=1

To solve the equation 4x = 46, there is another 8.4 △ x = 7

4X=46
X = 46 △ 4 (divide both sides by 4)
=23/2
=11.5
8.4÷X=7
X=8.4÷7
=1.2
