Question

5x+9=0 (2) 4x-(6-x)=13

Answer 1

5x+9=0
5x=-9/:5
x=-1,8

4x-(6-x)=13
4x-6+x=13
4x+x=13+6
5x=19/:5
x=3,8

Answer 2

Let's solve the given equations step by step.

Equation 1: 5x + 9 = 0

To solve for x, we need to isolate x on one side of the equation. Let's begin:

5x + 9 = 0 Subtract 9 from both sides: 5x = -9 Divide both sides by 5: x = -9/5 So the solution to equation 1 is x = -9/5 or -1.8.

Now let's move on to equation 2: 4x - (6 - x) = 13

First, simplify the expression within the parentheses:

4x - (6 - x) = 13 4x - 6 + x = 13 Combine like terms: 5x - 6 = 13

To isolate x, we'll add 6 to both sides:

5x - 6 + 6 = 13 + 6 5x = 19

Finally, divide both sides by 5:

x = 19/5

So the solution to equation 2 is x = 19/5 or 3.8.

Therefore, the solutions to the given equations are: Equation 1: x = -9/5 or -1.8 Equation 2: x = 19/5 or 3.8
