In a rectangle, one side equals x+10 and its opposite side equals 3y-3. The other side equals 2y and its opposite side equals x+7. Find x and y.

Question

anonymous · Answer

x+10=3y-3        
2y=x+7

anonymous · Answer

what properties does a rectangle have?

anonymous · Answer

both sides are parallel, and all angles are right angles.

anonymous · Answer

is that all?

anonymous · Answer

opposite sides are congruent, opposite angles are congruent, the diagonals of a rectangle are congruent

anonymous · Answer

so how might congruence help you here?

anonymous · Answer

the opposite sides

anonymous · Answer

How would I do the equation?

anonymous · Answer

i know its x+10=3y-3, 2y=x+7, how would i solve for x and y?

anonymous · Answer

solve each equation for y

anonymous · Answer

how?

anonymous · Answer

solve each for x, x is easier, get x alone for both equations

anonymous · Answer

did you get it for either equation?

anonymous · Answer

x=something

anonymous · Answer

could you set up the equation?

anonymous · Answer

you have 2 equations and two unknowns. the first one is x+10=3y-3 can you solve that one for x? so x=.....

anonymous · Answer

x=5

anonymous · Answer

maybe, tell me how you did it and ill tell you if your right or not

anonymous · Answer

or tell me y
