Answer:
the solution is undefined, no solutions
Step-by-step explanation:
A number equal to twice a smaller number plus 3.The same number is equal to twice the sum of a smaller number and 1
let the number be x
let the smaller number be y
interpreting the first line
A number equal to twice a smaller number plus 3
x = 2y+3
x-2y = 3
The same number is equal to twice the sum of a smaller number and 1
x = 2(y +1) = 2y +2
x-2y =2
x-2y = 3
x-2y =2
from equation i
x = 3+2y
insert it in equation i
x-2y = 3
3+2y-2y= 3
the solution is undefined
