5(7-X) = 31-x Como puedo resolverla ?
2 answers:
Answer:
x = 2
Step-by-step explanation:
5(7-x) = 31-x
You have to open the parenthesis on the left side so the new equation becomes:
35-5x = 31-x
now you have to move the numbers to one side and and variables to another so:
-5x+x = 31 - 35
-4x = -4
x = 1

x/2 + 10 = 35 - 2x
x/2 + 2x = 35 - 10
5x/2 = 25
5x = 25.2
5x = 50
x = 50/5
x = 10
The number is 10
