Question

Solve the equation
x-23=5(2x+3)-2

Answer 1

x=4.4

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 2

`x = - 4`

Explanation:

`x - 23 = 5(2x + 3) - 2 \\ x - 23 = 10x + 15 - 2 \\ - 23 - 15 + 2 = 10x - x \\ - 36 = 9x \\ ( - 36)/(9) = (9x)/(9) \\ - 4 = x`
