Answer:
Step-by-step explanation:
2y + 14x - 7x + 9y
2y + 9y + 14x - 7x
11y + 7x
5x + 9 = x - 23
move x to the other side
sign changes from +x to -x
5x-x+9= x-x-23 ( combine like terms)
5x-x+9= -23
4x+9= -23
move -9 to the other side
4x+9-9= -23-9
4x= -23-9
4x= -32
divide both sides by 4 to get x by itself
4x/4= -32/4
answer:
x= -8
Answer:
n=3
Step-by-step explanation:
So the question we are to solve is to be solved by collecting like terms and by division
So let's solve the question
-5n+8=-7
So let's solve
-5n+8=-7
Substrate 8 from both sides
-5n=-15
So let's make n the subject of formula by dividing both sides by -5
n=3
Therefore the final answer for the given question is 3
Answer:
Step-by-step explanation:
1) Change the mixed fractions into improper fractions:
2) Multiply the first fraction by 2/2 and the second fraction by 5/5 in order to create common factors on the denominator (You can do this because you are essentially multiplying by one, for example 2/2 = 1):
3) Simplify the numerator(top part) while keeping the denominator(bottom part) the same:
Answer:
-4
