x-(x+1)/2 =5

x - \frac{x + 1}{2} = 5

x = 11

Solution steps

x - \frac{x + 1}{2} = 5

Multiply both sides by

2

2 x - (x + 1) = 10

Expand

2 x - (x + 1) : x - 1

x - 1 = 10

Move

1

to the right side

x = 11

x, 3 y + x = 4

y, det (5 x) + 2 y = 19

9 x + 2 = 4 x + 12

4 \cdot (4 x + 2) = 17 - (4 x - 17)

y = - 2 (- 2) + 4
