Answer 1

Step-by-step explanation:

Question:

$(4xy + 3yz - 2xyz + 1) + (xy - 2yz) + (xyz) + (4) - (3xy + 2yz + 5xyz - 4)$

Solution:

Open the brackets:

$4xy + 3yz - 2xyz + 1 + xy - 2yz + xyz + 4 - 3xy - 2yz - 5xyz + 4$

Bring the like terms together to solve:

$4xy + xy - 3xy + 3yz - 2yz - 2yz - 2xyz - 5xyz+ xyz + 1 + 4 + 4$

$5xy - 3xy + 3yz - 4yz - 7xyz + xyz + 9$

$2xy - yz - 6xyz + 9 \: \: ans...$

Basic Algebra Formula

The general formulas used in algebra to solve algebraic equations and find the values of unknown variables are given here:

• a2 – b2 = (a – b)(a + b)
• (a+b)2 = a2 + 2ab + b2
• a2 + b2 = (a – b)2 + 2ab
• (a – b)2 = a2 – 2ab + b2
• (a + b + c)2 = a2 + b2 + c2 + 2ab + 2ac + 2bc
• (a – b – c)2 = a2 + b2 + c2 – 2ab – 2ac + 2bc
• (a + b)3 = a3 + 3a2b + 3ab2 + b3
• (a – b)3 = a3 – 3a2b + 3ab2 – b3

Basic Algebra Examples

Q 1: Find y, when, y + 15 = 30

Solution: y = 30 – 15

y = 15

Q 2 : Find x, when, 9x = 63

Ans. x = 63/9

x = 7

Q.3: If x/7 = 21, then find x.

Solution: Given x/7 = 21

or x = 21 x 7

x = 147
