Answer:

[ 5 ] -350 = 10x

[ 1 ] - 5 - 2 = ∛(10x + 7) + 2 - 2

[ 6 ] - 35 = x

[ 4 ] - 343 - 7 = 10x + 7 - 7

[ 3 ] - 343 = 10x + 7

[ 2 ] -7 = ∛(10x + 7)

Explanation:

The given equation is

[tex]-5=\sqrt[3]{10x+7}+2[/tex]

To solve the expression, we first need to subtract 2 from both sides

[tex]\begin{gathered} -5-2=\sqrt[3]{10x+7}+2-2 \\ -7=\sqrt[3]{10x+7} \end{gathered}[/tex]

Then, make each side to the power of 3, so

[tex]\begin{gathered} (-7)^3=(\sqrt[3]{10x+7})^3 \\ -343=10x+7 \end{gathered}[/tex]

Subtract 7 from both sides

[tex]\begin{gathered} -343-7=10x+7-7 \\ -350=10x \end{gathered}[/tex]

Divide both sides by 10

[tex]\begin{gathered} -\frac{350}{10}=\frac{10x}{10} \\ -35=x \end{gathered}[/tex]

Therefore, the order of the steps is

[ 5 ] -350 = 10x

[ 1 ] - 5 - 2 = ∛(10x + 7) + 2 - 2

[ 6 ] - 35 = x

[ 4 ] - 343 - 7 = 10x + 7 - 7

[ 3 ] - 343 = 10x + 7

[ 2 ] -7 = ∛(10x + 7)
