Answer:
John’s age is 8 years
Step-by-step explanation:
Let
x -----> John’s father's age
y -----> John’s age
z -----> John’s sister's age
we know that
-----> equation A
-----> equation B


-----> equation C
Substitute equation A and equation B in equation C and solve for y

Multiply by 2 both sides to remove the fraction



<em>Find the value of x</em>
<em>Find the value of z</em>

therefore
John’s father's age is 40 years
John’s age is 8 years
John’s sister's age is 4 years
Equations:
100 + 35m
50 + 35m
Steps:
100 + 35m = 50 + 35m <span>
<em>Set the equations equal to each other.</em>
</span> <span />
<span>
100 + 35m = 50 + 35m <span>
-50 - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>.
50+35m=35m
-35m -35m
<em>Subtract 35m from both sides of equation.</em>
50=m
