Sagot :

x = the age of Mr. Gilliam
His wife is 3 years older, so the age of Mr. Gilliam's wife = x+3
The sum of their ages is 95.

[tex]x+x+3=95 \\ 2x+3=95 \\ 2x=95-3 \\ 2x=92 \\ x=46[/tex]

Mr. Gilliam is 46 years old.

c= a+b
b= a-3


95= a+a-3
95=2a-3
98=2a
a= 49


b=49-3
b=46


This is a system of equations. The ages are 49 and 46. Mr. Gilliam is 46. Their ages are equal to 95 so I put two variables equal to 95. And one of the ages is 3 years younger than the other so I did another equation subtracting 3 from a variable. Then I plugged in the numbers! Check it out and ask me if you have questions! :)
