Question

Equação do 1 grau sendo u=q
5-a-11=4a-22?

2y+21-6y=-12+y-7?

3(x-2)-(1-x)=13?

6(4-t)-55=-5(2t+3)?

Answer 1

5 - a - 11 = 4a - 22

5 - 11 + 22 = 4a + a

28 = 5a

28/5 = a

2y + 21 - 6y = - 12 + y - 7

21 + 12 + 7 = 6y - 2y + y

40 = 5y

8 = y

3 (x - 2) - (1 - x) = 13

3x - 6 - 1 + x = 13

4x = 13 + 6 + 1

4x = 20

x = 5

6 (4 - t) - 55 = - 5 (2t + 3)

24 - 6t - 55 = - 10t - 15

- 6t + 10t = 55 - 24 - 15

4t = 16

t = 4
