Question

it’s 12pm I can’t do this anymore, help

Answer 1

$\\ \rm\longmapsto ST=TU$

$\\ \rm\longmapsto 8x+11=12x-1$

$\\ \rm\longmapsto 8x-12x=-1-11$

$\\ \rm\longmapsto -4x=-12$

$\\ \rm\longmapsto 4x=12$

$\\ \rm\longmapsto x=\dfrac{12}{4}$

$\\ \rm\longmapsto x=3$

Answer 2

The answer is x=3

8x + 11 = 12x - 1; subtract -12x
-4x + 11 = -1; subtract 11
-4x = -12; Divide by -4
x = 3
