x = 7 - 2 x

x = \frac{29 - 57}{8}

Decimal Notation

x = 2.68127 \dots

Solution steps

x = 7 - 2 x

Square both sides:

x = 49 - 28 x + 4 x^{2}

x = 49 - 28 x + 4 x^{2}

Solve

x = 49 - 28 x + 4 x^{2} : x = \frac{29 + 57}{8}, x = \frac{29 - 57}{8}

x = \frac{29 + 57}{8}, x = \frac{29 - 57}{8}

Verify Solutions:

x = \frac{29 + 57}{8}

False

, x = \frac{29 - 57}{8}

True

The solution is

x = \frac{29 - 57}{8}

5 x + 6 - 2 x = 3

13 - x = 5

316 = 240 \cdot N^{- 0.135135}

x + 105 = x + 15

143 + 26 z - z = 12
