Answer:
Step-by-step explanation:
Question (3)
The given expression is,
[tex]\frac{4(x-3)}{3}=20[/tex]
Statements Proof
1). [tex]\frac{4(x-3)}{3}=20[/tex] 1). Given
2). [tex]4(x-3)=60[/tex] 2). Multiplication property of equality
3). 4x - 12 = 60 3). Distributive property
4). 4x = 72 4). Addition property of equality
5). x = 18 5). Division property of equality
Question (4)
Equations are,
5x + 10 = 30 ------(1)
5(x + 10) = 30 ------(2)
From equation (1),
5x + 10 = 30
5x = 30 - 10
x = 4
From equation (2),
5(x + 10) = 30
(x + 10) = 6
x = 6 - 10
x = -4
Therefore, solutions of both the equations are different.
