(x-4.2) & #10135; 3 equals 8 solutions

(x-4.2) & #10135; 3 equals 8 solutions

The solution equation: 7-2 {3 [4 (x-1) - 8] - 20} = 11
You don't need to remove the brackets step by step, just move the one on the left to the right

7-2{3【4(x-1)-8】-20}=11
2{3【4(x-1)-8】-20}=-4
3【4(x-1)-8】-20=-2
3【4(x-1)-8】=18
4(x-1)-8=6
4(x-1)=14
x-1=7/2
x=9/2

Solve the equation: 20% x + 8 + ((20% x + 8) * 75%) + 113 equals X

20% x + 8 + ((20% x + 8) * 75%) + 113 equals X
0.2x + 8 + [ (0.2x + 8) ×0.75 ] + 113 ＝ x
0.2x + 8 + [ 0.15x + 6 ] + 113 = x
0.2x + 0.15x - x = -113 - 8 - 6
- 0.65x = - 127
X = 127 / 0.65 = 195 and 5 / 13

What is 20 divided by 80

√80=√16*5=4√5
So 20 / √ 80 = 20 / 4 √ 5 = √ 5 is about 2.23

144:80 = 1: X how much is x equal to

1.144:80=1:x
1.144x=80
X = 80 divided by 1.144
x=8000/1144
x=1000/143

How to calculate 80 - (100-x) cube = 60 Cube - x cube x

80²-(100-x)²=60²-x²
80²-60²=(100-x)²-x²
(80+60)(80-60)=(100-x+x)(100-x-x)
2800=100(100-2x)
28=100-2x
2x=72
x=36
