8 x - 7 = x - 7 + 4 x - 10

x = - \frac{10}{3}

Decimal Notation

x = - 3.33333 \dots

Solution steps

8 x - 7 = x - 7 + 4 x - 10

Add

7

to both sides

8 x - 7 + 7 = x - 7 + 4 x - 10 + 7

Simplify

8 x = x + 4 x - 10

Add similar elements:

x + 4 x = 5 x

8 x = 5 x - 10

Move

5 x

to the left side

3 x = - 10

Divide both sides by

3

x = - \frac{10}{3}

y, - x + 4 y = 4

- 20 - 4 c - 6 c = 2 (9 c + 19) - 2

3 (0) + 4 y = 12

x + 5 x - 5 = 2 x + 7

5 (x - 3) + 3 = 2 (2 x - 7) - 4
