Question

Resolva as equações:
b) y-3=12 c)z+4=15 d)c-5=11 e)d+2=14 f)e-6=13

Answer 1

Olá!!!

b) y-3=12

y−15=0

(1)⋅y+(−15)=0

y=−(−15)1

y=15

c)z+4=15

z−11=0  

(1)⋅z+(−11)=0

z=−(−11)1

z=11

e)d+2=14

d−12=0

(1)⋅d+(−12)=0

d=−(−12)1

d=12

f)e-6=13

e−19=0  

(1)⋅e+(−19)=0

e=−(−19)1

e=19
