Ajuda pfvrrr

Answer 1

Explicação passo-a-passo:

7x+16=23

7x=23-16

7x=7

X=7÷7

X=1

10X-18=32

10x=32+18

10x=50

X=50÷10

X=5

59x+12=13

59x=13-12

59x=1

X=1÷59

6(x+8)8(x+23)=134

6x+48+8x+184=134

6x+8x= 134-48-184

14x=-98

X= -98÷14

X= -7

12X + 14 = 25X + 188

12X - 25X = 188 - 14

-13X = 174

X= 174 ÷ -13

$x = \frac{174}{ - 13}$
