Question

4(3-h) - 11 = 7(2h - 5)

Answer 1

.......................

Answer 2

4(3-h)-11=7(2h-5)
12-4h-11=14h-35
1-4h=14h-35
-4h-14h=-35-1
-18h=-36
h=-36:(-18)
h=2
проверка:
4(3-2)-11=7(2*2-5)
4*1-11=7*(-1)
4-11=-7
-7=-7(в)
ответ:2

Answer 3

To solve the equation 4(3 - h) - 11 = 7(2h - 5), you'll need to follow these steps:

1. Distribute the constants outside the parentheses into the parentheses on both sides of the equation:

   4 * 3 - 4 * h - 11 = 7 * 2h - 7 * 5

2. Perform the multiplications and simplify:

   12 - 4h - 11 = 14h - 35

3. Combine like terms on both sides of the equation:

   (12 - 11) - 4h = 14h - 35

   1 - 4h = 14h - 35

4. To isolate the variable h on one side of the equation, you can start by adding 4h to both sides:

   1 - 4h + 4h = 14h - 35 + 4h

   1 = 18h - 35

5. Next, add 35 to both sides to isolate the term with h:

   1 + 35 = 18h - 35 + 35

   36 = 18h

6. Finally, divide both sides by 18 to solve for h:

   36 / 18 = 18h / 18

   h = 2

So, the solution to the equation is h = 2.
