</span></span></span>Steps:

<span>Multiply the second equation by -2, then add the equations together.

</span><span>(<span><span><span>2x</span>+<span>3y</span></span>=1</span>)

</span><span><span>−2</span><span>(<span><span>x+<span>4y</span></span>=<span>−2</span></span>)

</span></span>Becomes:

<span><span><span>2x</span>+<span>3y</span></span>=1

</span><span><span><span>−<span>2x</span></span>−<span>8y</span></span>=4

</span>Add these equations to eliminate x:

<span><span>−<span>5y</span></span>=5

</span>Then solve<span><span>−<span>5y</span></span>=5</span>for y:

<span><span><span>−<span>5y</span></span><span>−5</span></span>=<span>5<span>−5</span></span></span>(Divide both sides by -5)

<span>y=<span>−1

</span></span>Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

</span><span><span><span>2x</span>−3</span>=1</span>(Simplify both sides of the equation)

<span><span><span><span>2x</span>−3</span>+3</span>=<span>1+3</span></span>(Add 3 to both sides)

Answer:

Commutative

Step-by-step explanation:

Given

$3 + b + 2 = 3 + 2 + b$

Required

What law is applied

The applied law is commutative law of addition.

This law states that:

$a + b = b + a$

So:

$3 + b + 2 = 3 + (b + 2)$

When the positions of 2 and b are interchanged, we have:

$3 + b + 2 = 3 + (2 + b)$

Remove bracket

$3 + b + 2 = 3 + 2 + b$
