Question

2х-6=0 3х+1=7 3х+2х=10 7х+х+3=19 3х-1=2х

Answer 1

1)2x=6 x=3
2)3x=6 x=2
3)5x=10 x=2
4)8x=16 x=2
4)3x-2x=1 x=1

Answer 2

To solve these equations, let's go through each one step by step:

1. 2x - 6 = 0 To solve for x, we can add 6 to both sides of the equation: 2x - 6 + 6 = 0 + 6 2x = 6 Divide both sides by 2: (2x)/2 = 6/2 x = 3

2. 3x + 1 = 7 Subtract 1 from both sides of the equation: 3x + 1 - 1 = 7 - 1 3x = 6 Divide both sides by 3: (3x)/3 = 6/3 x = 2

3. 3x + 2x = 10 Combine the x terms on the left side of the equation: 5x = 10 Divide both sides by 5: (5x)/5 = 10/5 x = 2

4. 7x + x + 3 = 19 Combine the x terms and subtract 3 from both sides: 8x = 16 Divide both sides by 8: (8x)/8 = 16/8 x = 2

5. 3x - 1 = 2x Subtract 2x from both sides of the equation: 3x - 2x - 1 = 0 x - 1 = 0 Add 1 to both sides: x - 1 + 1 = 0 + 1 x = 1

So the solutions to the given equations are: x = 3, 2, 2, 2, 1 respectively.
