Answer:
x = -1
Step-by-step explanation:
- 10 + x + 4 - 5 = 7x - 5
-11 + x = 7x - 5
-6 + x = 7x
-6 = 6x
x= -1
Step 1: combine like terms
-10+x+4-5=7x-5----------> -10-5+4+x=7x-5-------->-11+x=7x-5
Step 2: Isolate the variable
-11+x=7x-5-------------> -11+5-x+x=7x-x+5-5-------> -6=6x
4x - 5(x + 3) Remove the brackets. Watch the - sign and -5*3
4x - 5x - 15 Combine the xs
-x - 15
The answer is to the question is 13
x+(-7) or (standard form)
