1. What is the solution set of the equation below?
|2x - 3|= 11
O A. {4}
O B.{7}
C. {-7,4}
D. {-4,7)
step 1
Find the solution of positive case
+(2x-3)=11
2x=11+3
2x=14
x=7
step 2
Find the solution of negatice case
-(2x-3)=11
Multiply by -1 both sides
2x-3=-11
2x=-11+3
2x=-8
x=-4
the solutions are x=7 and x=-4
therefore
tey answer is option B
