Question

A) 2x + 3x + 5 = 0;b) 3x +2y + 1 = 0;c) 4x + 3 = 0d) 8+ 4x0e) 3x+5x?+1=0​

Answer 1

Ответ:

а)2х+3х+5=0

5х=-5

х=-1

проверка:

-2-3+5=0

б)3х+2у+1=0

3х=-2у-1

в)4х+3=0

4х=-3

х=0,75

проверка:

4*0,75=3

г)8+4х=0 непонятно 4*0 или 4х=0, ладно,решим и так и так

8+4*0= 8

если 8+4х=0, то 4х=8  х=2

д) 3х+5х?+1=0

х=1

проверка

3+5-1+1=0

Answer 2

A) 2x+3x+5=0
5x= -5
x= -1
b) 3x+2y+1=0
3x= -2y-1
c) 4x+3=0
4x= -3
x= -0,75
d) 8+4x=0
4x= -8
x= -2
e) 3x+5x+1 =0
8x= -1
x = -1/8

Answer 3

It seems like you've provided a list of equations, and it looks like you want to either solve for the variables or simplify them. Let's go through each of them:

A) 2x + 3x + 5 = 0: Combine like terms: 5x + 5 = 0 Now, subtract 5 from both sides to solve for x: 5x = -5 Divide both sides by 5: x = -1

B) 3x + 2y + 1 = 0: This equation involves two variables, x and y. To solve for either x or y, you would need additional information or another equation.

C) 4x + 3 = 0: Subtract 3 from both sides: 4x = -3 Divide both sides by 4: x = -3/4

D) 8 + 4x0: It seems there is a typo in this equation. There should be an operator between 4x and 0 (e.g., 4x + 0 or 4x - 0) for it to be solvable.

E) 3x + 5x? + 1 = 0: It seems there's a typo in this equation as well. The "?" is not a valid operator or variable. Please provide the correct equation for me to solve it.

If you have any further questions or if you meant something different with equations D and E, please clarify, and I'd be happy to assist you further.
