Question :-

• Simply these expression and find their values if x =3, a=-1, b=-2.:

(i) 3x-5 -x +9

Answer :-

Simplify

$\boxed{ \sf \: 3x-5 -x +9}$

Put x =3, a=-1, b=-2

their is only X so we put X as 3

$\implies \sf \: 3 \times 3-5 -3 +9$

$\implies \sf \: 9 - 8 + 9$

$\implies \: 18 - 8$

$\implies \sf \: \large\boxed{10}$

BODMAS = B - Bracket first

• O - Of
• D - Divide
• M - Multiply
• A - Addition
• S - Subtraction
