Question

25 POINTS QUICK!!! could someone please help me with these two problems?? and possibly explain?? i need work too please! 25 POINTS

Answer 1

A.

4x+10=6x
-4x. -4x
——————-
10=2x
— —
2x 2x
= 5. The 2xs cancel out
* the sum of 2 angles =90 degrees


B

5x+13 = 3x+7
Subtract 3x on both sides ( always the less amount gets subtracted )
5x-3x =2x +13
3x-3x cancels out so you get +7
Now you have the equation 2x+13=7
-13 - 13
Subtract 13 to both sides ( opposite )
2x = 6
Divide by 2 and your answer is 6.

Answer 2

the first one A the sum of the angles are 10x+10 For the second one B the sum wud be 8x+20
