Question

Resolver as equações:

5 (x+2) -3 (x+6) = 6

y-3 + y-1 = y-1
 4       6      12

x+3 + x-1 = 8
 4        3

Answer 1

1) 5(x+2) -3(x+6) = 6
5x + 10 -3x -18 = 6
5x - 3x = 6 + 18 -10
2x = 14
x = 14/2
x = 7

2) y-3 + y-1 = y-1
y+y-y = -1 + 1 +3
y = 3

3) x+3 + x-1 = 8
x + x = 8 + 1 -3
2x = 9-3
x = 6/2
x = 3
