Question

6. Solve the following equations. (7 + 2x)/3 = (9x - 1)/7​

Answer 1

Answer:-

Lets solve

$\\ \sf{:}\longrightarrow \frac{7 + 2x}{3} = \frac{9x - 1}{7} \\ \\ \sf{:}\longrightarrow 7(7 + 2x) = 3(9x - 1) \\ \\ \sf{:}\longrightarrow 49 + 14x = 27x - 3 \\ \\ \sf{:}\longrightarrow 49 + 3 = 27x - 14x \\ \\ \sf{:}\longrightarrow 52 = 13x \\ \\ \sf{:}\longrightarrow 13x = 52 \\ \\ \sf{:}\longrightarrow x = \frac{52}{13} \\ \\ \sf{:}\longrightarrow x = 4$

Answer 2

Answer:

21+6x=64x-7

21+7=64x-6x

28=58x

x= 58/28
