Question

Como resuelvo eato:
1.- 5y+3=11+y
2.- 3x-4+8x=14+7x+x
3.- 6a-81+5a=65a+102+7a
4.- 14-12x+39x-18x=256-60x-657x
5.- x+3(x-1)=6-4(2x+3)

Answer 1

1)

5y + 3 = 11 + y

4y = 8

y = 2

2)

3x - 4 + 8x = 14 + 7x + x

11x - 4 = 14 + 8x

3x = 10

x = 10/3

3)

6a - 81 + 5a = 65a + 102 + 7a

11a - 81 = 72a + 102

62a = 183

a = 183/62

4)

14 - 12x + 39x - 18x = 256 - 60x - 657x

14 - 9x = 256 - 717x

726x = 242

x = 242/726

5)

x + 3 (x+1) = 6 - 4 (2x + 3)

x + 3x + 3 = 6 - 8x + 12

4x + 3 = 18 - 8x

12x = 15

4x = 5

x = 5/4
