Answer:
x=1
Step-by-step explanation:
5x+9 - x= 13
Combine like terms
4x +9 = 13
Subtract 9 from each side
4x+9-9 = 13-9
4x = 4
Divide each side by 4
4x/4 = 4/4
x=1

Answer:
12
Step-by-step explanation:
the ratio of the 2 numbers = 3 : 4 = 3x : 4x ( x is a multiplier ) , then
3(3x) + 2(4x) = 68 , that is
9x + 8x = 68
17x = 68 ( divide both sides by 17 )
x = 4
smaller number = 3x = 3 × 4 = 12
