So find the difference between 1995 and 2022 to make it easier 2022-1995=27
so the rephrased question is when hazel was x years old, she was 25 years older than son gary who was y old at that time (equation is x is 25 more than y or x=25+y) in 27 years, (this means x+27 and y+27) hazel's age will be 150% of gary's age (x+27= 150% of y+27) percent means parts out of 100 so 150%=150/100=15/10=1.5 'of' in math means multiply so the equations are x=25+y x+27=1.5(y+27) subsitute 25+y for x in second euation 25+y+27=1.5(y+27) add like terms y+52=1.5(y+27) I personally dislike decimals to multiply both sides by 2 to make 2 0.5's or 1 (you are technically supposed to distribute or divide both sides by 1.5) so 2y+104=3(y+27) distribute 2y+104=3y+81 subtract 2y from both sides 104=y+81 subtract 81 from both sides 23=y subsitute x=25+y x=25+23 x=48
