Question

4×x=21654000:x=3x:12000=4x-415=326990-x=176

Answer 1

$4 \times x = 216 < = > x = \frac{216}{4} = 54 \\ \\ 54000 \div x = 3 < = > x = \frac{54000}{3} = 18000 \\ \\ x \div 12000 = 4 < = > x = 12000 \times 4 = 48000 \\ \\ x - 415 = 326 < = > x = 326 + 415 = 741 \\ \\ 990 - x = 176 < = > x = 990 - 176 = 814$

Answer 2

To solve the equation, let's go step by step:

1. 4×x = 21654000 To solve for x, divide both sides by 4: x = 21654000 / 4 x = 5413500

2. x = 3x / 12000 Multiply both sides by 12000 to get rid of the fraction: 12000x = 3x Subtract 3x from both sides to isolate x: 12000x - 3x = 0 Factor out x from the left side: x(12000 - 3) = 0 Simplify: 11997x = 0 Divide both sides by 11997 to solve for x: x = 0

3. 4x - 415 = 326990 To solve for x, add 415 to both sides: 4x = 326990 + 415 4x = 327405 Divide both sides by 4 to find x: x = 327405 / 4 x = 81851.25

4. x = 176 No calculation needed as x is already given.

So, the solutions for x in each equation are as follows:

1. x = 5413500
2. x = 0
3. x = 81851.25
4. x = 176
