Justify each step with a property of algebra, put the correct property for each equation 5(2y−3)−4y=8−2y−15(what’s the property of this?)
5(2y−3)−4y=−2y−7(what’s the property of this?)
5(2y−3)=2y−7 (what’s the property of this?)
10y−15=2y−7 (what’s the property of this?)
8y=8 (what’s the property of this?)
y=1 (what’s the property of this?)

Two triangles that are similar figures has equal and ratio of corresponding sides.Also, the corresponding angles of two similar triangles are equal. We can solve this problem using this principle.
AB/DE=BC/EF=CA/FD
As well as the corresponding angles are equal.
∠ABC=∠DEF
∠BCA=∠EFD
∠CAB=∠FDE
