Answer:11
Step-by-step explanation:y negative is not the common squared but x is so you do math x=yx5=11
7/4 - 5/3
(7/4)*(3/3) - (5/3)*(4/4)
(7*3)/(4*3) - (5*4)/(4*3)
21/12 - 20/12
= (21 - 20)/12 = 1/12
Answer:
(8,-1)
Step-by-step explanation:
Given :
To Find: solution of given system of equations.
Solution:
Equation a :
Equation b :
Substitute the value of y from equation b in equation a
y from equation b : y = 7-x
Now substitute value of y in equation a
Thus equation a becomes:
⇒ x= -1 and x = 8
Now substitute values of x in equation b to obtains values of y
⇒
for x = -1
⇒
⇒
⇒
Thus (x,y)=(-1,8)
For x =8
⇒
⇒
⇒
Thus (x,y)=(8,-1)
Hence Option A is the correct solution .
