Answer:
-7/3 =x
Step-by-step explanation:
5x-15 = 8x-8
Subtract 5x from each side
5x-5x-15 = 8x-5x-8
-15 = 3x-8
Add 8 to each side
-15+8 = 3x-8+8
-7 = 3x
Divide each side 3
-7/3 = 3x/3
-7/3 =x
Answer:
look its really simple like if there is written the father age is two times than its son and its is also said sum of their age becomes 25 then
Step-by-step explanation:
solution,
let father and son age be x and y
2x =y ---------------(i)
x+y=25----------------(ii)
now,
putting the value of y in equation two we get,
x+(2x)=25
3x=25
x=25/3
x=8 yrs ( using round off)
again,
2x = y
2×8=y
16=y
therefore, father age is 16 and son age is 8

Answer:
g=-1
Step-by-step explanation:
3(g+4)=9
Divide both sides by 3.
g+4= 9/3
Divide 9 by 3 to get 3.
g+4=3
Subtract 4 from both sides.
g=3−4
Subtract 4 from 3 to get −1.
g=−1
