Question

a) 3(×-2) -5(2-3×)= 4(2× - 6)

b) 9× = 6× + 12

c) 5× - 1 = 3× + 11

d) 2× + 8 = × +13

pfv me ajudaaaaaa é urgente ​

Answer 1

a) 3x-6 - 10+15x = 8x-24

3x+15x-8x = -24+10+6

10x = -8

x = -8/10   x=-0,8

b) 9x-6x = 12

3x = 12

x=12/3   x=4

c) 5x-3x = +11+1

2x = 12

x=12/2   x=6

d) 2x-x = 13-8

x = 5
