Question

alguem me ajuda com essas equações por favor

a) 8t + 30= 62 f) 2z - 15= 3
b) 3m + 25= 40 g) 7y - 1= 20
c) 4s + 26= 50 h) 6c - 12= 0
d) 5n + 18= 53 i) 9p - 35= 55
e) 10w + 14= 94 j) 8r - 6= 2​

Answer 1

$a)8t + 30 = 62$

$8t = 62 - 30$

$8t = 32$

$t = \frac{32}{8}$

$\boxed{ t = -4}$

$b)3m + 25 = 40$

$3m = 40 - 25$

$3m = 15$

$m = \frac{15}{3}$

$\boxed{ m = -5}$

______________________________________

$c)4s + 26 = 50$

$4s = 50 - 26$

$4s = 24$

$s = \frac{24}{4}$

$\boxed{ s = 6}$

______________________________________

$d)5n + 18 = 53$

$5n = 53 - 18$

$5n = 35$

$n = \frac{35}{5}$

$\boxed{ n = 7}$

______________________________________

$e)10w + 14 = 94$

$10w = 94 - 14$

$10w = 80$

$w = \frac{80}{10}$

$\boxed{ w = 8}$

______________________________________

$f)2z - 15 = 3$

$2z = 3 + 15$

$2z = 18$

$z = \frac{18}{2}$

$\boxed{ z= 9}$

______________________________________

$g)7y - 1 = 20$

$7y = 20 + 1$

$7y = 21$

$y = \frac{21}{7}$

$\boxed{ y = -3}$

______________________________________

$h)6c - 12 = 0$

$6c = 0 + 12$

$6c = 12$

$c = \frac{12}{6}$

$\boxed{ c = 2}$

______________________________________

$i)9p - 35 = 55$

$9p = 55 + 35$

$9p = 90$

$p = \frac{90}{10}$

$\boxed{ p = 10}$

______________________________________

$j)8r - 6 = 2$

$8r = 2 + 6$

$8r = 8$

$r = \frac{8}{8}$

$\boxed{ r= 1}$
