J=john's age now
s=sam's age now
j=3 times s
j=3s
in five years (j+5,s+5)
j+5=2 times (5+s)
j+5=2(s+5)
j+5=2s+10
subtract 5 from both sides
j=2s+5
use other equation
j=3s
j=2s+5
subsitute
3s=2s+5
subtract 2s
s=5
sam=5
j=3s
j=3 times 5
j=15
john=15
sam=5

Answer:
I believe the final answer is x=3
Step-by-step explanation:
when trying to solve equations, always sort things out and prioritize things, that way it's easier to get to the final answer.
x+2x-5=4
3x-5=4 just move the -5 to the other side and make it a positive
3x=9
x+y=4
y=1
3+1=4
Answer:
m = 299
Step-by-step explanation:
When isolating variables, you must do the same thing to both sides of the equation. To isolate "m", you must add 77 to both sides.
m - 77 = 222 <----- Original equation
+77 +77 <----- Add 77 to both sides
m + 0 = 299 <----- Resulting equation
m = 299 <----- Rewrite
