pfv pra hj ❤
$2. \times - 3 = 5 =$

​

Answer 1

Explicação passo-a-passo:

(a)2.×-3=5

2x = 5 + 3

2x = 8

x = 8/2

x = 4

(b)y:3+5=12

y+15=36

y=36-15

y=21

(c)5.z+4=24

5z = 24 - 4

5z = 20

z = 20/5

z = 4

(d)m:2-5=1

m-2=10

m=10+2

m=12

(e)3.n-9=15

3n = 15 + 9

3n = 24

n = 24/3

n = 8

(f)p:4+12=40

p+48=160

p=160-48

p=112

(g)q:2-14=8

q-28=16

q=16+28

q=44

(h)3.r-22=2

3r = 2 + 22

3r = 24

r = 24/3

r = 8

(i) 4.e+12=40

4e = 40 - 12

4e = 28

e = 28/4

e = 7
