4 x + 7 = x + 2

x = 3, x = - 3

Decimal Notation

x = 1.73205 \dots, x = - 1.73205 \dots

Solution steps

4 x + 7 = x + 2

Square both sides:

4 x + 7 = x^{2} + 4 x + 4

4 x + 7 = x^{2} + 4 x + 4

Solve

4 x + 7 = x^{2} + 4 x + 4 : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions:

x = 3

True

, x = - 3

True

The solutions are

x = 3, x = - 3

a - 1 - 7 - a = 1

x = x + 4

x^{\frac{1}{2}} - 3 = 0

x^{\frac{1}{2}} - 3 = 5

2 x + 5 + 4 = 0
