Question

Tìm x:

125 + 5 ( x - 7 ) = 130

Answer 1

5 ( x - 7 ) = 5

x - 7 = 1

=> x = 8

Answer 2

\(5.\left(x-7\right)=130-125=5\)

\(x-7=1,x=8\)

Answer 3

=>5(x-7)=5

=>x-7=1

hay x=8

Answer 4

\(\Rightarrow5\left(x-7\right)=5\\x-7=1\\ x=7+1\\ x=8 \)

Answer 5

X=7

 

Answer 6

=>5(x-7)=130-125

5(x-7)=5

x-7=5:5

x-7=1

x=7+1=8

vậy x=8

Answer 7

x - 7 = 130 - 125

x -7 = 5

x -  7 = 5:5

x - 7 =1

x      = 1 + 7

x      = 8
