Question

-4(5-4x)=x+1 ????????????????????

Answer 1

-4(5-4x)=x+1

-20+16x=x+1

16x-x=20+1

15x=21

x=7/5=1,4

Answer 2

Ответ:

$x=1.4$

Объяснение:

$-4(5-4x)=x+1\\\\-20+16x=x+1\\\\16x-x=1+20\\\\15x=21\\\\x=\frac{21}{15} \\\\x=1.4$

Answer 3

Let's solve the equation -4(5-4x) = x+1 step by step.

1. Start by distributing the -4 on the left side of the equation: -4 * 5 + 4 * 4x = x + 1

2. Simplify the expressions on both sides: -20 + 16x = x + 1

3. Move the x term from the right side to the left side by subtracting x from both sides of the equation: -20 + 16x - x = 1

4. Simplify the x terms on the left side: 15x - 20 = 1

5. Add 20 to both sides of the equation to isolate the term with the variable on the left side: 15x - 20 + 20 = 1 + 20

6. Simplify both sides: 15x = 21

7. Finally, divide both sides by 15 to solve for x: (15x)/15 = 21/15 x = 7/5

So, the solution to the equation is: x = 7/5
