Answer:
-1/3 is number one
Step-by-step explanation:
rearrange it so that instead of 19 - 9x = 22 it is -9x + 19 = 22 then subtract 19 from both sides of the equation then simplify.
Answer:
A
Step-by-step explanation:
solving the original equation
19 - 9x = 22 ( subtract 19 from both sides )
- 9x = 3 ( divide both sides by - 9 )
x = [tex]\frac{3}{-9}[/tex] = - [tex]\frac{1}{3}[/tex]
solving Maryanne's equation
- [tex]\frac{12}{5}[/tex] x + [tex]\frac{26}{5}[/tex] = 6 ( multiply through by 5 to clear the fractions )
- 12x + 26 = 30 ( subtract 26 from both sides )
- 12x = 4 ( divide both sides by - 12 )
x = [tex]\frac{4}{-12}[/tex] = - [tex]\frac{1}{3}[/tex]
solving Herb's equation
11 = 18x + 5 ( subtract 5 from both sides )
6 = 18x ( divide both sides by 18 )
[tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex] = x
Only Maryanne's equation has the same solution as the original equation
