Question

responda as equações:
3(x + 6) = 5x + 8
5(x + 2) = 2(x - 1)
4.(x + 3) - X = 24 + x​

Answer 1

a) x = 5

b) x = 4

c) x = 6

a) 3(x+6) = 5x+8

3x+18 = 5x+8

3x-5x = 8-18

-2x = -10

x = 10/2

x = 5

b) 5(x+2) =2(x-1)

5x+10 = 2x-2

5x-2x = -2-10

3x = -12

x = -12/3

x = 4

c) 4(x+3)-x = 24+x

4x+12-x = 24+x

4x-x-x = 24-12

2x = 12

x = 12/2

x = 6
