Answer:

x=4.4

Step-by-step explanation:

expand the brackets

10x+15

full equation now

=x-23=10x+15-2 this makes it more simpler to find like terms

+2 on both sides

=x-25=10x+15

=+25 on both sides

x=10x+40

= -x on both sides

=9x=40

40/9=x

x=4.4

Answer:

x =  - 4

Step-by-step explanation:

x - 23 = 5(2x + 3) - 2 \\ x - 23 = 10x + 15 - 2 \\  - 23 - 15 + 2 = 10x - x \\  - 36 = 9x \\  \frac{ - 36}{9}  =  \frac{9x}{9}  \\  - 4 = x

ICE Princess25 [194]

Answer:

x = \frac{83}{36}

Step-by-step explanation:

Given

x - 2 \frac{1}{4} = \frac{1}{18} ( change mixed number to improper fraction )

x - \frac{9}{4} = \frac{1}{18}

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = \frac{83}{36}
