Step-by-step explanation:
on the left side u add 4k+3k=7k
on the right side u subtract 2k-6k=4k
then on the left side u add 2 to each side and u get rid of the 2 on the left side
on the right side u add 5+2=7
then on the right side u add 4k on each side and get rid of the 4k on the right
on the left u subtract 7k-4k=3k
on both sides divide by 3
Step-by-step explanation:
I assume the question is asking for Eric's grandfather age now.
Let Eric's age now be x. Then Eric's grandfather age now is (x + 55).
In 7 years, Eric's age will be (x + 7) and Eric's grandfather age will be (x + 62).
We know that (x + 62) = 6(x + 7).
x + 62 = 6x + 42
5x = 62 - 42 = 20
x = 4.
Answering the question: Eric's grandfather age now is (4 + 55) = 59 years old.
