Question

3-4(3-x)=1 и 4x-(3x+1)=-x

Answer 1

Ответ:

Пошаговое объяснение:

если это 2 уравнения, то

3-12+4х=1                                4х-3х-1=-х

4х=1+12-3                                4х-3х+х=1

4х=10                                        2х=1

х=2,5                                         х=0,5

Answer 2

1)3-4(3-x)=1
3-12+4x-1=0
4x-10=0
4x=10
x=2.5
2)4x-(3x+1)=-x
4x-3x-1+x=0
2x=1
x=0.5

Answer 3

To solve the equations, let's simplify and solve each one step by step:

1. 3 - 4(3 - x) = 1

First, distribute the -4 on the term inside the parentheses:

3 - 4 * 3 + 4x = 1

Now, simplify further:

3 - 12 + 4x = 1

Combine like terms:

-9 + 4x = 1

Now, isolate the variable (x) by moving the constant term to the other side:

4x = 1 + 9

4x = 10

Finally, divide both sides by 4 to solve for x:

x = 10 / 4

x = 2.5

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

First, distribute the negative sign on the terms inside the parentheses:

4x - 3x - 1 = -x

Combine like terms:

x - 1 = -x

Now, isolate the variable (x) by moving the constant term to the other side:

x + x = 1

2x = 1

Finally, divide both sides by 2 to solve for x:

x = 1 / 2

x = 0.5

So the solutions for the two equations are:

x = 2.5 and x = 0.5
