Question

3X + 7 upon 4 x + 5 is equal to 3 upon 5 ​

Answer 1

Step-by-step explanation:

$\frac{3x + 7}{4x} + 5 = \frac{3}{5} \\ \\ \frac{3x + 7 + 20x}{4x} = \frac{3}{5} \\ \\ \frac{23x + 7}{4x} = \frac{3}{5} \\ \\ 5(23x + 7) = 3 \times 4x \\ \\ 115x + 35 = 12x \\ \\ 115x - 12x = - 35 \\ \\ 103x = - 35 \\ \\ x = \frac{ - 35}{103}$

Answer 2

Answer:

=(3x+7)/(4x+5)=3/5

=(3x+7)×5=3×(4x+5)

=15x+35=12x+15

=15x-12x=15-35

=3x=-20

=x=-20/3

=x=-6.66
