Question

resolva :y-36=25 x+6=11 /// 2x/3 + 4x/3 = 4 /// x/2+5 para x = 8 /// /// x/2 - x/3 + 10 para x = 12 /// 5x-3=3x-11 /// 4x-15=-2x+3

Answer 1

y - 36 = 25

y = 25 + 36

y = 61

x + 6 = 11

x = 11 - 6

x = 5

2x/3 + 4x/3 = 4

6x/3 = 4

6x = 4 × 3

6x = 12

x = 12/6

x = 2

x/2+5 para x = 8

8/7

x/2 - x/3 + 10 para x = 12

12/2 - 12/3 + 10

6 - 4 + 10

12

5x - 3 = 3x - 11

5x - 3x = - 11 + 3

2x = - 8

x = - 8/2

x = - 4

4x - 15 = - 2x + 3

4x + 2x = 3 + 15

6x = 18

x = 18/6

x = 3
