One number is 15 more than another. The sum of twice the larger and 3 times the smaller is 182. find the numbers. 2 variables

Question

campbell_st · Answer

the numbers are x and x + 15

then 3(x) + 2(x + 15) = 182

then 3x + 2x + 30 = 182

              5x = 152

                x = 30.4

x + 15 = 45.4

the numbers are 30.4 and 45.4

yea but you have to use 2 variables like x and y

campbell_st · Answer

write it in 1 variable.... x the smaller and x + 15 the larger.... its easier than 

3x + 2y = 182
y = x + 15

then its still the same problem

using substitution

3x +2(x +15) = 182

5x + 30 = 182
