What property justifies that 6x+9/3 =2x + 3? (see the pic of how the fraction is)

spayn [35]

Answer:

C. Distributive property

Step-by-step explanation:

Distributive property says that

$a\cdot (b+c)=a\cdot b+a\cdot c$

Consider left part of the expression

$\dfrac{6x+9}{3}=\dfrac{1}{3}\cdot (6x+9)$

By distibutive property,

$\dfrac{1}{3}\cdot (6x+9)\\ \\=\dfrac{1}{3}\cdot 6x+\dfrac{1}{3}\cdot 9\\ \\=2x+3$

Which equation shows the variable terms isolated on one side and the constant terms isolated on the other side for the equation

Andrej [43]

Answer:

$5x= 15$

Step-by-step explanation:

Given

$3x - 5 = -2x +10$

Required

Write the variables and constants on different sides

$3x - 5 = -2x +10$

Add 2x to both sides

$2x + 3x - 5 =2x -2x +10$

$5x - 5 =10$

Add 5 to both sides

$5x - 5 + 5 = 10 + 5$

$5x= 10 + 5$

$5x= 15$

Hence, the equation is

$5x= 15$

Solving further [divide both sides by 5]

$x = 3$
