🧮 सरल गणित / Reasoning - Algebra Basics Cheat Sheet 8. Simple Equation 1 Whot is Algebro? Algebra uses letters (varidbles) to Rerwue variable with given value represent numbers Evaluate: | 2x + 5 = 13 Common variables: X 9a b Exomple:' 2x =13 - 5 Variable Unknown quantity २x = 8 X=4 2. Algebraic Expressions Expression combination of 4 Like & Unlike_Terms voriobles ond rumbers sume vuriable & power Like termS Example 2a~7, <2 +49- 3x + 5 Unlike terms + different Variables Terms ore joined bU powers Qr 3. Terms Coefficient & Constont X (like) Example 3K, -5x, (unlike) 2x, 2y, 12 [n expression: 79 4X = Term Combine only_like termsl 2 Term Constant Term 6 Algebroic Identitics Coefficients &-7 Constont (no vorioblel 12 b)2 02 + 2db + 02 (० + 5. Basic Operations )2 = 42 २ab + b२ (a - Aodiion & subtroction > combine Iike terms 5) = 02 b)(a b2 multiply coefficients & variables Multiplication Importont Identities divide coefficients (6 =2 = 3x) Division' 8. Simple Linear Equation (Rules written step-wise) QX + b = C Substitution Method Solve by moving constants to one side Isolate varidble Repluce vurioble with given value Exumple: 2x + 5 = 13 Evdluote expression 2X = 13 _ 5 Exomple: If x=3, find 2x+5. 2x = 8 2(3)+5 = 6+5 =11. 7 X=4 9. Important Observotions 10 Common Mistokes X Mixing like & unlike terms: Same operation on both sides keeps Sign equation balanced errors Signs chgnge when lerm crusses X Forgetting suuore on terms sign Wrong substitution Rule: LHS RHS Algebra Basics Cheat Sheet 8.
