Question

a)12x-x+10=3 b)-2x+10x=24 c)15x+x-9=11

Answer 1

a) 12x-x+10=3
11x=3-10
11x=-7
x= -7/11

b) -2x+10x=24
8x=24
x=24/8
x=3

c) 15x+x-9=11
16x=11+9
16x=20
x=20/16

Answer 2

OI

a) 12x - x + 10 = 3

12x - x = 3 - 10

11x = - 7

x = - 7/11

b) - 2x + 10x = 24

8x = 24

x = 24/8 ÷ 8

x = 3

c) 15x + x - 9 = 11

16x = 11 + 9

16x = 20

x = 20/16==>simplifica por 4

x = 5/4
