Answer 1

Explicación paso a paso:

1) 24 + 15 = B +9

24+15-9= b

30= b

2) (2 x R ) + 12 = 20

2r+12= 20

2r= 20-12

2r= 8

R=8/2

R= 4

3) 573 = P + 18

573-18=p

555= p

4) 13+ Q = 156

Q= 156-13

Q= 143

5)=E= 2x10

E= 20

6)n+ 20 = 859

N= 859-20

N= 839

7) P-2569 = 210

P= 210+2569

P= 2779

8) 20 x Z = 220​

20z= 220

Z= 220/20

Z= 11
