Question

I just need the properties in order help plz

Answer 1

$\: \: \: \:$

$6x - 30 - 3x = - 12$

• move the variable to the left hand side and change its sign, move the constant to the right hand side and change its sign

$6x - 30 = - 12$

• collect like terms and calculate the sum

$3x = - 18$

• divide both sides of the equation by 3

$x = 3$

hope it helps

Answer 2

$\sf \longmapsto6(x−5)=3x−12$

• Simplify both sides

$\sf \longmapsto(6)(x)+(6)(−5)=3x+−12$

$\sf \longmapsto6x+−30=3x+−12$

$\sf \longmapsto \: 6x - 30 = 3x - 12$

• Subtract 3x from both sides

$\sf \longmapsto \: 6x−30−3x=3x−12−3x$

$\sf \longmapsto3x−30=−12$

• Add 30 to both sides

$\sf \longmapsto3x−30+30=−12+30$

$\sf \longmapsto3x=18$

• Divide both sides by 3

$\sf \longmapsto \: \dfrac{3x}{3} = \dfrac{18}{3}$

$\sf \longmapsto \: x = 6$

$\boxed{\sf \: x = 6 }$
