(12) (1 + x) + (2) (1 - 4 x) = 40

x = \frac{13}{2}

Decimal Notation

x = 6.5

Solution steps

(12) (1 + x) + (2) (1 - 4 x) = 40

12 (1 + x) + 2 (1 - 4 x) = 40

Expand

12 (1 + x) + 2 (1 - 4 x) : 4 x + 14

4 x + 14 = 40

Move

14

to the right side

4 x = 26

Divide both sides by

4

x = \frac{13}{2}

x, 6 x + 11 y = 44

4 (3) - 5 (- 4) = - 13

y, 2 x - 4 y = 20

- 5 x = - 15

- 6 = s + 6
