Question

Three times a number and five times another number . Added together make 169 when five times frist number and three times second number added together make 159 write the given fact as two equation find the numbers

Answer 1

let the first number be x
and second number be y
according to the problem,
3x+5y=169
5x+3y=159
multiple the eq 1 with 5 and eq with3 then we get
15x+25y=845
15x+9y=477
do subtraction
16y=368
y=23
substitute y=23 in eq 3
15(x)+25(23)=845
15x=845-575
x=270/15
=18
x=18 and y=23 these are the values of x and y
