Question

resolva as equações

1) 3x+5=44

2) x+8=9-x

3) 4x-5x=5x-5x+6

4) 13x-18=4x​

Answer 1

1) 3x+5=44

3x = 44 - 5

3x = 39

x = 39/3

x = 13

2) x+8=9-x

x + x = 9 - 8

2x = 1

x = 1/2

3) 4x-5x=5x-5x+6

4x - 5x - 5x + 5x = 6

-x = 6

x = -6

4) 13x-18=4x​

13x - 4x = 18

9x = 18

x = 18/9

x = 2
