Question

X-9=72; 3×x=18; 12+x=81; x÷6=48 надо решить уравнение​

Answer 1

х-9=72

x=72+9

x=81

провер. 81-9=72

3•х=18

х=18:3

x=6

провер. 3•6=18

12+x=81

x=81-12

x=69

пров.12+69=81

х:6=48

х=48•6

х=288

провер.

288:6=48

Answer 2

To solve each of the equations, you need to find the value of 'x' that satisfies the equation. Let's solve each equation step by step:

1. X-9=72 Add 9 to both sides to isolate 'X': X = 72 + 9 X = 81

2. 3×x=18 Divide both sides by 3 to isolate 'x': x = 18 ÷ 3 x = 6

3. 12+x=81 Subtract 12 from both sides to isolate 'x': x = 81 - 12 x = 69

4. x÷6=48 Multiply both sides by 6 to isolate 'x': x = 48 × 6 x = 288

So the solutions to the equations are as follows:

1. X = 81
2. x = 6
3. x = 69
4. x = 288
