Question

13. What is the solution of 2|2x - 1-8 = 18?

X= -6 or X= 7
x=9/4 or x=27/4
X=-6 or X= 27/4
X= 27/4 or X= 7

Answer 1

1×x−1−8=18

2 Simplify 1\times x1×x to xx.

x-1-8=18x−1−8=18

3 Simplify x-1-8x−1−8 to x-9x−9.

x-9=18x−9=18

4 Add 99 to both sides.

x=18+9x=18+9

5 Simplify 18+918+9 to 2727.

x=27x=27
