Question

3∙(х-4) - (5-2х)=17?

Answer 1

3×(х-4)-(5-2х)=17

3х-12-5+2х=17

5х-17=17

5х=17+17

5х=34

х=34/5

Answer 2

To solve the equation 3∙(x-4) - (5-2x) = 17, you can follow these steps:

1. Distribute the 3 on the left side of the equation:

3(x) - 3(4) - (5 - 2x) = 17

2. Simplify the equation by performing the multiplications:

3x - 12 - (5 - 2x) = 17

3. Remove the parentheses by distributing the negative sign:

3x - 12 - 5 + 2x = 17

4. Combine like terms on the left side:

(3x + 2x) - 12 - 5 = 17

5x - 12 - 5 = 17

5. Continue to simplify by combining the constants:

5x - 17 = 17

6. Add 17 to both sides of the equation to isolate the variable on one side:

5x - 17 + 17 = 17 + 17

5x = 34

7. Finally, divide by 5 to solve for x:

5x/5 = 34/5

x = 34/5

So, the solution to the equation is:

x = 6.8
