Question

4x+2(1-3x)=13 4(5x+2)=10(2x-3)=15

Answer 1

4x+2(1-3x)=13
4x+2-6x=13
-2x+2=13
-2x=13-2
-2x=11
X=-11/2 или -5,5

4(5x+2)=10
20x+8=10
20x=10-8
20x=2
X=1/10 или 0,1

(2x-3)=15
2x=15+3
2x=18
X=9

Answer 2

Let's solve these two equations step by step:

1. 4x + 2(1 - 3x) = 13

First, distribute the 2 on the left side:

4x + 2 - 6x = 13

Combine like terms by subtracting 2 from both sides:

4x - 6x = 13 - 2

-2x = 11

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

x = -11/2

So, the solution to the first equation is x = -11/2.

2. 4(5x + 2) = 10(2x - 3) + 15

First, distribute on both sides:

20x + 8 = 20x - 30 + 15

Now, let's simplify the equation:

20x + 8 = 20x - 15

Next, let's move all the x terms to one side by subtracting 20x from both sides:

8 = -15

This equation is not possible. It means there is no solution for x that satisfies the second equation. The two sides of the equation are always unequal, so there are no values of x that make it true.

So, for the second equation, there is no solution for x.
