Question

X+1=4 2 -1,4*(x-6)=7*(4x+1,2) x-8=7 x+2 3

Answer 1

х+1=4;

х=4-1;

х=3.

-1,4*(х-6)=7*(4х+1,2);

-1,4х-8,4=28х+8,4;

-1,4х-28х=8,4+8,4;

-29,4х=16,8;

х=-16,8/29,4.

х-8=7;

х=7+8;

х=15.

х+2=3;

х=3-2;

х=1.

Answer 2

It seems there are multiple equations provided. Let's solve each of them step by step:

1. Equation 1: X + 1 = 4 To solve for X, we need to isolate X on one side of the equation. Here's how we do it:

X + 1 = 4 Subtract 1 from both sides: X = 4 - 1 X = 3

So, the solution for the first equation is X = 3.

2. Equation 2: 2 - 1.4 * (X - 6) = 7 * (4X + 1.2) Let's simplify and solve for X:

2 - 1.4 * (X - 6) = 7 * (4X + 1.2)

First, distribute the 1.4 and 7: 2 - 1.4X + 8.4 = 28X + 8.4

Now, move all X terms to one side and constant terms to the other side: -1.4X - 28X = -8.4 - 2

Combine like terms: -29.4X = -10.4

Now, isolate X by dividing both sides by -29.4: X = -10.4 / -29.4

X ≈ 0.353

So, the solution for the second equation is X ≈ 0.353.

3. Equation 3: X - 8 = 7X + 23 Let's solve for X in this equation:

X - 8 = 7X + 23

First, move all X terms to one side and constant terms to the other side: X - 7X = 23 + 8

Combine like terms: -6X = 31

Now, isolate X by dividing both sides by -6: X = 31 / -6

X ≈ -5.17

So, the solution for the third equation is X ≈ -5.17.

4. Equation 4: X + 2 = 3 To solve for X, isolate it on one side:

X + 2 = 3 Subtract 2 from both sides: X = 3 - 2 X = 1

So, the solution for the fourth equation is X = 1.

To summarize:

1. X = 3
2. X ≈ 0.353
3. X ≈ -5.17
4. X = 1
