Question

5*(x-3)+7(2x+5)=2(x-7)

Answer 1

Ответ:

Объяснение:

5*(x-3)+7(2x+5)=2(x-7)

5x-15+14x+35=2x-14

5x-15+14x+35-2x+14=0

17x+34=0

17x= -34

x= -2

Answer 3

To solve for the value of x in the equation 5*(x-3) + 7*(2x+5) = 2*(x-7), you'll need to simplify and solve for x step by step. Here's how you can do it:

1. Start by distributing the constants outside the parentheses:

5x - 15 + 14x + 35 = 2x - 14

2. Combine like terms on both sides of the equation. Add and subtract terms to isolate the x terms on one side and the constants on the other side:

(5x + 14x) - 15 + 35 = 2x - 14

19x + 20 = 2x - 14

3. Now, subtract 2x from both sides of the equation to move all the x terms to one side:

19x - 2x + 20 = -14

17x + 20 = -14

4. Next, subtract 20 from both sides of the equation:

17x = -14 - 20

17x = -34

5. Finally, divide both sides by 17 to isolate x:

x = -34 / 17

x = -2

So, the solution to the equation is x = -2.
