b) 9+4X=9²-40
c) 2X-2+X=4
D) 23+4X+15=5³+3⁰
E) 10X+18-14=22+4X
​

Answer 1

Respuesta:

4; 8; 2; 22; 3

Explicación paso a paso:

a) 2(2x-3) = 6+x

4x-6 = 6+x

4x-x = 6+6

3x = 12

x = 4

b) 9+4x = 9²-40

4x = 81-40-9

4x = 32

x = 8

c) 2x-2+x = 4

3x = 4+2

3x = 6

x = 2

d) 23+4x+15 = 5³+3⁰

4x = 125+1-23-15

4x = 88

x = 22

e) 10x+18-14 = 22+4x

10x - 4x = 22-18+14

6x = 18

x = 3
