Answer:
I think its 40 if i did it right Ill show you how i did it
Step-by-step explanation:
First I added 12+12 and the is 24.
The I added 8+8 and that was 16.
Lastly I added 16+24= 40
Option I
(3x+4)cm =(2x+10)cm
3x-2x=6
x=6
Option II
(3x+4)= (x+12)
3x-x=12-4
2x=8
x=4
Option III
(2x+10)= (x+12)
2x-x=12-10
x=2
Answer:
x=0, y=-3
Step-by-step explanation:
Input x=y+3 into 6x-5y=15 to get:
6(y+3)-5y=15
Solve for y
6y+18-5y=15
y+18=15
y=-3
Plug in y to get x
Step-by-step explanation:
whats the equation lol
X=number of years that Ethas was 5 times older than his son.
we suggest this equation:
40-x=5(12-x)
40-x=60-5x
-x+5x=60-40
4x=20
x=20/4=5
answer. 5 years.
