Answer:
w = -12
Step-by-step explanation:
w/6 + 5/8 = -1 3/8
Subtract 5/8 from each side
w/6 + 5/8-5/8 = -1 3/8 - 5/8
w/6 = -1 3/5 - 5/8
w/6 = -1 8/8
w/6 = -2
Multiply by 6 on each side
w/6 *6 = -2*6
w = -12

Answer:


Step-by-step explanation:
Given
Let
f = Father's age
s = Son's age
We'll solve this question, while reading through the instructions
From the first statement;
f is 2 less than 7 times s.
This means

In two years time, the father will be f +2 and the son will be s + 2
So, their sum is:


Collect like terns


So, the equations are:
