Question

Resolva as equações

A)X +15 = 35
B)3Y -4 = 28
C): 2.(W -2)= 16
D)3z - 10 = Z +60

Answer 1

Resposta:

a) x = 20

b) y = 32/3 ou 10,6666667

c) w = 10

d) z = 35

Explicação passo-a-passo:

a) $x+15=35\\x=35-15\\x=20$

b) $3y-4=28\\3y=28+4\\3y=32\\y=32/3$

c) $2(w-2)=16\\2w-4=16\\2w=16+4\\2w=20\\w=20/2\\w=10$

d) $3z-10=z+60\\3z-z=60+10\\2z=70\\z=70/2\\z=35$
