1(4x+7y)+2(5y-9x)
=4x+7y+10y-18x
=-14x+17y
The solution is -14x+17y.
Answer:
Step-by-step explanation:
If X + 3y + 7 is squared by 3y then your answer should be X + 3y sq. + 7 = 10x sq.
Answer:
1 because then he would eat 6 in 6 hours .-.
We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have 
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.
