i did it out of 100 i choose 25/100
then id you simplified that 25 goes into 100 4 times 25 goes into int self one time so the answer is 1/4
Answer:
x = 3 and y = -1
Step-by-step explanation:
It is given that,
3x + 2y = 7 ----(1)
2x - 5y = 11 ---(2)
<u>To find the solution of given equations</u>
eq(1) * 2 ⇒
6x + 4y = 14 ----(3)
eq(2) * 3 ⇒
6x - 15y = 33 ----(4)
eq(3) - eq(4) ⇒
6x + 4y = 14 ----(3)
<u>6x - 15y = 33 </u> ----(4)
19y = 19
y = -1
Substitute the value of y in eq (1) we get,
3x + 2y = 7 ----(1)
3x + (2 *-1) = 7
3x = 7 + 2 = 9
x = 9/3 = 3
Therefore x = 3 and y = -1
