Question

01 - Resolva as equações isolando a variável . a) 3x + 4 = 65 b) x - 16 = 32 c) 5x + 41 = 4x + 72 d) 3 ( x + 2 ) = 15

Answer 1

$a) 3x + 4 = 65$

$3x = 65 - 4$

$3x = 61$

$x = \color{red} \frac{61}{3}$

______________________________________

$b) x - 16 = 32$

$x = 32 + 16$

$x = \color{red}48$

______________________________________

$c) 5x + 41 = 4x + 72$

$5x - 4x = 72 - 41$

$x = \color{red}31$

______________________________________

$d) 3 ( x + 2 ) = 15$

$x + 2 = 5$

$x = 5 - 2$

$x = \color{red}3$
