I'm not really sure if this is correct but I hope this helps:)
Step-by-step explanation:
By Geometric mean property:
<u>Answer:</u> x = 1/5 and y= -7/5
Step-by-step explanation: Let's solve your system by elimination.
Multiply the first equation by -3,and multiply the second equation by 1.
-3 (x - 2y = 3)
1 (3x - y = 2)
Becomes:
-3x + 6y = -9
3x -y = 2
Add these equations to eliminate x:
5y = -7
Then solve 5y = -7
5y/7 = -7/5
y = -7/5
Now that we‘ve found y, let’s plug it back in and solve for x.
Write down an original equation:
x - 2y = 3
<h3>
Substitute -7/5 for y in x - 2y = 3:</h3><h3>
x - 2 (-7/5) = 3</h3><h3>
x + 14/5 = 3</h3><h3>
x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)</h3><h3>
x = 1/5</h3><h3><u>
Answer: </u></h3><h3>x = 1/5 and y = -7/5</h3><h3 /><h3 /><h3 />
Answer:
(5,14)
Step-by-step explanation:
4x-6=2x+4 because I chose any of the y values
change of subjects ⬇️
4x-2x =4+6
2x=10
2x÷2 and 10÷2
⬆️ making x stand alone
x= 5
put x into any of the equation
y=2(5)+4
y= 10+4
y=14
Answer:
4÷5 is the answer
