4.) 2(x-1)+3= 2x+1

Distribute the 2, multiply the 2 by x and -1.

2*x= 2x (all you need to do is put 2 in front of x)

2*-1= -2

2x-2+3= 2x+1

Combine like terms. 

2x+1=2x+1

Subtract one on both sides. 

2x=2x

Divide by 2 into both sides. 

x=1

We can check this by plugging it in. 

2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works

I hope this helps!

<em>Angle </em><em>ADG,</em><em> </em><em>angle</em><em> </em><em>BEH </em><em>and </em><em>angle</em><em> </em><em>CFI,</em><em> </em><em>all </em><em>have </em><em>two </em><em>curves</em><em> </em><em>in </em><em>their</em><em> </em><em>angles</em><em>.</em><em> </em><em>Same </em><em>number</em><em> of</em><em> </em><em>curves</em><em> </em><em>are </em><em>used</em><em> </em><em>to </em><em>represent</em><em> </em><em>that </em><em>their</em><em> </em><em>measure</em><em> </em><em>are </em><em>equal</em><em>.</em><em> </em>

So, m angle CFI = m angle ADG

So, m angle CFI = m angle ADG=> m angle CFI = 92°
