Question

X+54=88,8 X-0,7=1,43 10X+0,3X=0,7004 2,1X=0,147 0,385:X=0,35

Answer 1

Х+54=88,8
х=88,8-54
х=34,8

х-0,7=1,43
х=1,43+0,7
х=2,13

10х+0,3х=0,7004
10,3х=0,7004
х=0,7004÷10,3
х=0,068

2,1х=0,147
х=0,147÷2,1
х=0,07

0,385÷х=0,35
х=0,385÷0,35
х=1,1

Answer 2

To solve each equation for X, follow these steps:

1. X + 54 = 88.8: Subtract 54 from both sides to isolate X: X = 88.8 - 54 X = 34.8

2. X - 0.7 = 1.43: Add 0.7 to both sides to isolate X: X = 1.43 + 0.7 X = 2.13

3. 10X + 0.3X = 0.7004: Combine the X terms on the left side: 10X + 0.3X = 10.3X Now divide both sides by 10.3 to solve for X: X = 0.7004 / 10.3 X ≈ 0.068

4. 2.1X = 0.147: Divide both sides by 2.1 to solve for X: X = 0.147 / 2.1 X ≈ 0.07

5. 0.385 / X = 0.35: To solve for X, divide both sides by 0.35: X = 0.385 / 0.35 X ≈ 1.1

So the solutions for each equation are:

1. X ≈ 34.8
2. X ≈ 2.13
3. X ≈ 0.068
4. X ≈ 0.07
5. X ≈ 1.1
