Find the square root of both sides
√y²= √(144/169)
y= √144 / √169
y= 12/13
Final answer: y=12/13
Answer: x= 5
Step-by-step explanation:
Plug the second equation into the first equation’s y.
3x-2(-2x+7)=21
Then use distribution
3x+4x-14=21
Add 4x and 3x
7x-14=21
Then add 14 to both sides
7x=35
Divide by 7 to get x
35/7=5
x=5
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Solve:</u>
- 4/7 + 8/3
- = 12/21 + 56/21
- =
- = 3 5/21.
- = 68/21.
