Answer:
No, they are not equal
Step-by-step explanation:
3(2x + 5) - (3x – 4)
Lets simplify this expression
Distribute
6x +15 -3x +4
3x +19
This is not the same as 3x+11
They are not equivalent
x=-2
y=2
_________
Step-by-step explanation:
get the upper x on the opposite side or to be with y
5x+y=-8 / *(-7)
2x+7y=10
__________
-35+2x=56+10
2x+7y=10
__________
-33x=66 x=-2
-4+7y=10
y=2
Answer:

4)
Step-by-step explanation:
1) Since the whole angle is , and to find the other angle, which is labeled as , you subtract from :
2) Since you already have two angle measures and , you add them up and subtract it from to get the angle measure for :
3) Same thing from number 1. Subtract from :
4) Same thing from number 2. Add and and subtract it from :
