Question

Resolva as equações a seguir:

a) x - 20 = 35 c) 2x - 43 = 65 + x

b) 10y - 10 = 6y + 6 d) 3(x + 4) = 2x + 15​

Answer 1

$\large{a)x - 20 = 35}$

$\large{x = 35 + 20}$

$\large \boxed{ \: \red{ x = 55 }}$

________________________________

$\large{b)10y - 10 = 6y + 6}$

$\large{10y - 6y = 6 + 10}$

$\large{4y= 16}$

$\large{y = \frac{16}{4} }$

$\large \boxed{ \: \red{ y = 4 }}$

________________________________

$\large{c)2x - 43 = 65 + x}$

$\large{2x - x = 65 + 43}$

$\large \boxed{ \: \red{ x = 108}}$

________________________________

$\large{d)3(x + 4) = 2x + 15}$

$\large{3x + 12 = 2x + 15}$

$\large{3x - 2x = 15 - 12}$

$\large \boxed{ \: \red{ x = 3 }}$
