Question

Quanto q vale x nessa equação?
5•(2x-3) -2•(4-3x) =4x+1
Esse • ê a multiplicação!!!

Answer 1

$\LARGE\tt{}5(2x - 3) - 2(4 - 3x) = 4x + 1 \\ \LARGE\tt{}10x - 15 - 2(4 - 3x) = 4x + 1 \\ \LARGE\tt{}10x - 15 + 8 + 6x = 4x + 1 \\ \LARGE\tt{}16x - 15 - 8 = 4x + 1 \\ \LARGE\tt{}16x - 23 = 4x + 1 \\ \LARGE\tt{}16x - 23 - 4x = 1 \\ \LARGE\tt{}16x - 4x = 1 + 23 \\ \LARGE\tt{}12x = 1 + 23 \\ \LARGE\tt{}12x = 24 \\ \\ \LARGE\tt{}x = \dfrac{24}{12} \\ \\ {\large\boxed{\boxed{  { \LARGE \green{\tt x = 2} }}}}$

Bons estudos!
