Answer:
a =
Step-by-step explanation:
Given
G = 4ca - 3ba ← factor out a from each term on the right side
G = a(4c - 3b) ← divide both sides by (4c - 3b)
a =

ANSWER
B. x=3,y=2
EXPLANATION
The given equations are
and
We add the two equations to eliminate y.
This implies that that:
Simplify:
Divide both sides by 2.
We put x=3 into any of the equations to find y.
Let us substitute x=3 into equation (1) to get:
Divide both sides by -3 to get;
The solution is therefore x=,y=2.
Let's assume
number of small notebooks =x
number of large notebooks =y
we are given
total number of notebooks =31
so, we get
now, we can solve for y
we have
Small notebooks cost $3.50 and large notebooks cost $5.00
she has $134 to spend
so, we get
now, we can plug y
now, we can find y
so,
number of small notebooks is 14
number of large notebooks is 17.............Answer
