Question

4(x+5)=1/3(3x+9)=???
3(x+5)/4(2x-7)=9

​

Answer 1

$\huge\mathfrak\pink{Answer}$

$4(x + 5) \: = \: \frac{1}{3} (3x + 9)$

$\frac{4x + 20}{1} = \frac{3x + 9}{3}$

★By Cross Multiplication:-

$4x + 20 × 3 = 3x + 9 × 1$

$240 = 3x + 9$

$240 - 9 = 3x$

$231 = 3x$

$x \: = \cancel \frac{231}{3}$

$x \: = \: 77$

$\frac{3(x + 5)}{4} (2x - 7) \: = 9$

─────────────────────

$\frac{3x+15}{4}$ $(2x-7)=9$

$16x-21x+30x+105= 9$

$16x+30x-21x+105=9$

$36x-21x+105=9$

$15x+105=9$

$15x+105=9$

$15x=9-105$

$15x=-96</h2><h2></h2><h2>x=$ $\cancel\frac{-96}{15}$

$x=-6.4$
