solve equations by substitution

Solve the Systems of linear equations by Method of Substitution: 2x - 9y = 0 (i) x - 18y = 27 (ii..

Substitution Method - Solve 2x - 9y = 0 (i) x - 18y = 27 (ii) From (i) 2x - 9y = 0 2x = 9y (iii) Substituting this value of x in (ii), we get, 9y - 36y = 54 - 27y = 54 y = -2 Substitute this value of y in (iii): = -..

Solve the system of equation by substitution: 3 x - y + 2 z = - 2, y + 3 z = 3, and 2 z = 4 => x = -3, y = 3, z = 2 or x = 3, y = -3, z = 2 or x = -3, y = 3, z = -2 or x = -3, y = -3, z = 2..

In this type of substitution, an electrophile attacks the carbanion of the substrate substituting one of the hydrogens or other group..

The reactions in which an atom or group of atoms in a molecule is replaced or substituted by different atoms or group of atoms are called substitution reaction. For example, In substitution reactions the hydrogen of the alkane molecule is replaced by another..

The reactions in which an atom or group of atoms in a molecule is replaced or substituted by different atoms or group of atoms are called substitution reaction. For example, These reactions can be of two types: ..

At elevated temperatures (500°C), higher alkenes give substitution products with chlorine. For example, CH 3 -CH=CH 2 + Cl 2 ClCH 2 -CH=CH 2 +HCl propene 3-chloropropene Branched-chain alkenes give substitution..

Electrophilic Substitution - The nitro group strongly deactivates the benzene ring towards electrophilic substitution. Nitro group is electron withdrawing group and thus causes electron deficiency at ortho and para positrons as is clear from the resonating structures of nitro be..

If the integrand f(x) of the integral is not in an integral form the variable of integration x is changed to a suitable variable z by substitution and on differentiation and simplification, the new integral is found integrable. ..
