Answer:
4x+3y=23
Step-by-step explanation:
4x+3y=23
2x+6y=34 multiply equation by 2 to get x values equivalent, so
4x+12y=68 now subtract firs equation from this
-(4x+3y=23)
so 9y=45 and y=5
now find x:
4x+3(5)=23
4x+15=23
4x=8
x=2
So, hamburgers cost $2 and chicken nuggets $5.
Answer:
Step-by-step exmndndbdbdxplanation:
It is easily b because you have to subtract the demensions and you get 8 squared
X+ (x+2)+ (x+4)= -21
3x+6=-21
3x=-27
x=-9
Final answer: -9, -7, -5
