Question

I'm unsure for each process, the options are: -Addition property of equality - Subtraction property of equality - Multiplication property of equality -Division property of equality -Simplifying - distributive

Answer 1

Given an equation below and evaluate the process:

`5(3x+4)=-10`

Step 1: Multiplication property of equality inorder to open the bracket

`\begin{gathered} 5(3x+4)=-10 \\ 15x+20=-10 \end{gathered}`

Step 2: Subtraction property of equality:

`\begin{gathered} 15x+20=-10 \\ \text{subtract both side by 20} \\ 15x+20-20=-10-20 \\ 15x=-30 \end{gathered}`

Step 3: Division property of equality:

`\begin{gathered} 15x=-30 \\ \text{divide both side by 15} \\ (15x)/(15)=-(30)/(15) \\ x=-2 \end{gathered}`

Step 4: Simplfying:

`x=-2`

Therefore the correct value of x = -2
