<em>7x </em><em>=</em><em> </em><em>133</em>

<em>x=</em><em> </em><em>19</em>

<em>the </em><em>numbers </em><em>are </em><em>:</em>

Answer:

57 and 76

Step-by-step explanation:

Given the ratios are 3 : 4 = 3x : 4x, then

3x + 4x = 133

7x = 133 ( divide both sides by 7 )

x = 19

The numbers are

3 × 19 = 57 and 4 × 19 = 76
