Solve |2x + 1| = 10 {9/2, 11/2} {-9/2, 9/2} {-11/2, 9/2}

1 answer:

6 0

The answer is -11/2, 9/2

Explanation

You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10

Then you solve for X in each equation.
2x+1=10 would give you 9/2

2x+1=-10 would give you -11/2

So your final solutions would be x1= -11/2 x2= 9/2
