Question

4(2x+5)-(4x-3)=18-2x 7(-3(x-2)-x)-12=4(5-3x)-4

Answer 1

8х + 20 -4х -3=18-2х

6х=1

х = 1/6

7(-3х+6-х)-12=20-12х-4

-21х+42 -7х -12 =16-12x

-28x+12x=-14

-16x=-14

x=14/16

x=7/4

Answer 2

Let's solve the equations step by step:

1. 4(2x+5)-(4x-3)=18-2x

Start by distributing the 4 on the left side:

8x + 20 - (4x - 3) = 18 - 2x

Remove the parentheses:

8x + 20 - 4x + 3 = 18 - 2x

Combine like terms:

8x - 4x + 20 + 3 = 18 - 2x

Simplify further:

4x + 23 = 18 - 2x

Move the terms involving x to one side and the constants to the other side:

4x + 2x = 18 - 23

Combine like terms:

6x = -5

Divide both sides by 6:

x = -5/6

Therefore, the solution to the equation is x = -5/6.

2. 7(-3(x-2)-x)-12=4(5-3x)-4

Start by simplifying the expressions inside the parentheses:

7(-3x + 6 - x) - 12 = 4(5 - 3x) - 4

Multiply through the parentheses:

-21x + 42 - 7x - 12 = 20 - 12x - 4

Combine like terms:

-28x + 30 = 20 - 12x - 4

Move the terms involving x to one side and the constants to the other side:

-28x + 12x = 20 - 4 - 30

Combine like terms:

-16x = -14

Divide both sides by -16:

x = -14 / -16

Simplify the fraction:

x = 7/8

Therefore, the solution to the equation is x = 7/8.
