Question

5a-(3a+5)+2a-4= 8x-4=3x+11=

Answer 1

8 х -4 = 3 х + 11
8 х - 3 х = 11 +4
4 х = 15
х = 15 : 4
х = 3,75



5 а - ( 3 а + 5 ) + 2 а - 4
5 а - 3 а - 5 + 2 а -4
2 а -5 + 2 а - 4
2 а - 2 а + -4 + 5
а + 1
а = 1 а

Answer 2

It seems like you've written three separate equations. Let's solve each of them step-by-step:

1. 5a - (3a + 5) + 2a - 4 = 0

First, let's simplify the equation:

Combine like terms: 5a - 3a - 5 + 2a - 4 = 0 (5a - 3a + 2a) - (5 + 4) = 0 4a - 9 = 0

Now, isolate 'a': Add 9 to both sides of the equation: 4a = 9

Finally, divide both sides by 4 to find the value of 'a': a = 9/4

2. 8x - 4 = 3x + 11

To solve for 'x', we need to isolate the variable 'x' on one side of the equation:

Subtract 3x from both sides: 8x - 3x - 4 = 3x - 3x + 11 5x - 4 = 11

Add 4 to both sides of the equation: 5x = 11 + 4 5x = 15

Finally, divide both sides by 5 to find the value of 'x': x = 15/5 x = 3

3. There appears to be an error in the third equation. It seems like there might be a missing variable or operator. If you could provide the correct equation, I'd be happy to help you solve it.
