Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
Answer: 5/4c
Step-by-step explanation:
Hi, to answer this question we simply have to solve the equation given:
Coefficients are the numbers next to the variable; in this case, the variable is c.
c + 25/ 100c
1/1 c +25/100c
100/100c +25/100 c
125/100 c
5/4c

Answer:
The measure of the angles are 137 and 43
Step-by-step explanation:
Firstly, we need to understand what is meant by saying two angles are supplementary.Two angles are termed supplementary if the addition of the value of both angles equal 180.
Now let the two angles we are seeking in this question be x and y respectively
We write our first equation using the supplementary information;
x + y = 180 •••••••••••(i)
Secondly we are made to know that the difference between these angles is 94
Mathematically;
x - y = 94
or simply x = 94 + y; insert this into equation 1 above
94 + y + y = 180
2y = 180 - 94
2y = 86
y = 86/2
y = 43
x = 94 + y = 94 + 43 = 137
