Lets get started :)
2 + 2 + x - 7 = 21
11 + x = 21
We have to subtract 11 on both sides to isolate x
11 ( - 11 ) + x = 21 ( - 11 )
11 and 11 cancels out
x = 10
115:55 bc if you divide them both you fat the same answer which is 2
Answer:
3x + 4y = 8
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = 2 - 
( multiply through by 4 to clear the fraction )
4y = 8 - 3x ( add 3x to both sides )
3x + 4y = 8 ← in standard form
Answer:
6, 3
Step-by-step explanation:
Let the number of bags that he would have been used to put 3 kg of apples be x. Thus the number of bags that would be used to put 2kgs will therefore be (x+9), hence the total number of kgs the bags will hold will be given by:
3*x=3x kgs
2(x+9)=(2x+18) kgs
since the total weights are the same then:
2x+18=3x
hence
18=3x-2x
18=x
thus the number of bags required to put 3 kgs of apples will be 18. Thus the total Kgs of apples was:
3x
=3*18
=54 kgs
