Question

rezolvati in multimea n si z ecuatiile
3x-4=6-x
1-8x=x-5
3+y=-2y-60

Answer 1

3x - 4 = 6 - x

3x + x = 6 + 4

4x = 10 => x = 5/2

1 - 8x = x - 5

1 + 5 = x + 8x

6 = 9x

x = 2 / 3

3 + y = -2y - 60

y + 2y = - 60 - 3

3y = - 63

y = -21

Answer 2

3x-4=6-x

3x+x=6+4

4x=10

x=10/4⁽²=5/2

1-8x=x-5

-8x-x=-5-1

-9x=-6

x=-6/-9⁽³=2/3

3+y=-2y-60

y+2y=-60-3

3y=-63

y=-63/3=-21
