Answer: 56 times
Step-by-step explanation:
Ill edit this later to answer the question, but what is the question???
So 5+x=47
subtract 5 from both sides
x=42
not 52
the answer is 42
1) 1/3x - 2/3 = -18
2) 1/3x - 2/3 + 2/3 = -18 + 2/3
3) 1/3x = -54/3 + 2/3
4) 1/3x = -52/3
5) (1/3x) divided by 1/3 = -52/3 divided by 1/3
6) x = -52/3 x 3/1
7) x = -52
Answer:
a)7, b)-40
Step-by-step explanation:
a) 5(x-1)=30
=>5x -5=30
=>5x=30+5
=>5x=35
=>x=35/5
so, x=7
b)3(x+10)-2(x-5)=0
=>3x+30-2x+10=0
=>x+40=0
so,x=-40
