Question

3x=-6; x+3=6; 4x-4=x+5; 5x-8=2x+4?

Answer 1

Ответ:

1)3х=-6

х=-2

2)х+3=6

х=6-3

х=3

3)4х-4=х+5

4х-х=5+4

3х=9

х=3

4)5х-8=2х+4

5х-2х=4+8

3х=12

х=4

Answer 2

It seems like you've provided a set of equations. Let's solve each equation one by one:

1. $3x = -6$: Divide both sides by 3 to isolate $x$: $x = -6 / 3 = -2$

2. $x + 3 = 6$: Subtract 3 from both sides to isolate $x$: $x = 6 - 3 = 3$

3. $4x - 4 = x + 5$: Subtract $x$ from both sides and add 4 to both sides to isolate $x$: $3x = 9$ Divide both sides by 3: $x = 9 / 3 = 3$

4. $5x - 8 = 2x + 4$: Subtract $2x$ from both sides and add 8 to both sides to isolate $x$: $3x = 12$ Divide both sides by 3: $x = 12 / 3 = 4$

So, the solutions for the given equations are:

1. $x = -2$
2. $x = 3$
3. $x = 3$
4. $x = 4$
