Question

1.x+9=0 2.x+5=12 3.3x+7=4 4.3x-1=8 5.7+4x=5x

Answer 1

1.) X=0-9
X=-9

2)X=12-5
X=7

3) 3X=(4-7)
3X=-3
X=-3/3
X=1

4) 3X=8+1
3X=9
X=3

5) 7=5X-4X
7=X
X=7

Answer 2

To solve each of these equations for the value of x, follow these steps:

1. x + 9 = 0 Subtract 9 from both sides: x = -9

2. x + 5 = 12 Subtract 5 from both sides: x = 12 - 5 x = 7

3. 3x + 7 = 4 Subtract 7 from both sides: 3x = 4 - 7 3x = -3 Divide both sides by 3: x = -3 / 3 x = -1

4. 3x - 1 = 8 Add 1 to both sides: 3x = 8 + 1 3x = 9 Divide both sides by 3: x = 9 / 3 x = 3

5. 7 + 4x = 5x Subtract 4x from both sides: 7 = 5x - 4x 7 = x

So, the solutions for each equation are:

1. x = -9
2. x = 7
3. x = -1
4. x = 3
5. x = 7
