Step-by-step explanation:
2+9-18/3x2-10
Lets follow order of ops.
/, x, +, -
Divide first.
2 + 9 - (18/3) x 2 - 10
2+9-6x2-10
Now we multiply.
2+9-(6x2)-10
2+9-12-10
Add.
11-22
Now subtract.
11-22=-11

Answer:
Step-by-step explanation:
Solution by substitution method
3x+5y=7
and 4x-y=5
Suppose,
3x+5y=7→(1)
and 4x-y=5→(2)
Taking equation (2), we have
4x-y=5
⇒y=4x-5→(3)
Putting y=4x-5 in equation (1), we get
3x+5y=7
⇒3x+5(4x-5)=7
⇒3x+20x-25=7
⇒23x-25=7
⇒23x=7+25
⇒23x=32
⇒x=32/23
→(4)
Now, Putting x=32/23
in equation (3), we get
y=4x-5
⇒y=4(32/23)-5
⇒y=(128-115)/23
⇒y=13/23
∴y=13/23 and x=32/23
