Question

1)3х+2=3,5х-2.2)2х-2,2=4х+4,8

Answer 1

1) 3×+2=3.5×-2

3×-3.5×=-2-2

-0.5×=-4

×=8

2×-2.2=4×+4.8

2×-4×=4.8+2.2

-2×=7

×=3.5

Answer 2

To solve these equations, you need to isolate the variable x on one side of the equation. Here are the steps for each equation:

1. 3x + 2 = 3.5x - 2

First, you can start by moving all the terms with x to one side of the equation and the constants to the other side:

3x - 3.5x = -2 - 2

Now, combine like terms:

-0.5x = -4

Next, divide both sides by -0.5 to isolate x:

(-0.5x) / (-0.5) = (-4) / (-0.5)

x = 8

So, the solution to the first equation is x = 8.

2. 2x - 2.2 = 4x + 4.8

Similarly, move all the terms with x to one side and the constants to the other side:

2x - 4x = 4.8 + 2.2

Combine like terms:

-2x = 7

Now, divide both sides by -2 to isolate x:

(-2x) / (-2) = 7 / (-2)

x = -3.5

So, the solution to the second equation is x = -3.5.
