a-1=sqrt(7-a)

Solution

a - 1 = 7 - a

Solution

a = 3

Solution steps

a - 1 = 7 - a

Square both sides:

a^{2} - 2 a + 1 = 7 - a

a^{2} - 2 a + 1 = 7 - a

Solve

a^{2} - 2 a + 1 = 7 - a : a = 3, a = - 2

a = 3, a = - 2

Verify Solutions:

a = 3

True

, a = - 2

False

The solution is

a = 3

Popular Examples

sqrt((x-4)^2)+sqrt((1-x)^2)=7

(x - 4)^{2} + (1 - x)^{2} = 7

10x+sqrt(x)-2=0

10 x + x - 2 = 0

sqrt(-x^2+25)+x=1

- x^{2} + 25 + x = 1

x = 5

2sqrt(2x+1)-2x=1

2 2 x + 1 - 2 x = 1
