Question

5×a-(8+12)=20 решить уравнение

Answer 1

5а -8 - 12 = 20
5а = 20 + 8 + 12
5а = 40
а = 40 : 5
а = 8

Answer 2

5*а-(8+12)=20
5*а=20+20
5*а=40
а=40:5
а=8
------------------
5*8-(8+12)=20
20 =20

Answer 3

To solve the equation 5×a-(8+12)=20, we will use the following steps:

1. Simplify the expression on the left side of the equation by combining like terms:

   5a - (8 + 12) = 20 5a - 20 = 20

2. Add 20 to both sides of the equation to isolate the variable on one side:

   5a - 20 + 20 = 20 + 20 5a = 40

3. Divide both sides of the equation by 5 to solve for a:

   5a/5 = 40/5 a = 8

Therefore, the solution to the equation 5×a-(8+12)=20 is a = 8.
