Tyler tried to solve an equation step by step. \qquad\begin{aligned} 3(x+4)&=-18 \\ 3x+12&=-18&\green{\text{Ste p } 1} \\ 3x&=-30&\blue{\text{Step } 2} \\ x&=-10&\purple{\text{Step } 3} \end{aligned} 3(x+4) 3x+12 3x x =−18 =−18 =−30 =−10 Step 1 Step 2 Step 3

Given that:

Tyler tried to solve an equation step by step as:

To find: Consider we need to find Tyler mistake (if any) and property used for each step.

Solution:

In the given steps, all steps are correct.

In Step 1, Distributive property is used.

In Step 2, Subtraction property of equality is used.

In Step 3, Division property of equality is used.

won't that be plagrisim thought?

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
