Answer:
7(8x+5) ≠48x+35 when x = 2.
That is; the two expressions are not equivalent when x = 2
Step-by-step explanation:
To solve this, we need to follow the steps below
We will substitute x = 2 in the first expression and simplify, then we will now substitute x =2 in the other expression and simplify, at the end of the simplification, we will compare the two expression to see if they are equal.
First lets open up the bracket, that is; 7(8x + 5)=56x + 35
Now substitute x = 2 in 56x + 35
56 x + 35 = 56(2) + 35 = 112 + 35 = 147
56 x + 35 = 147 when x = 2
Next is to substitute x = 2 in 48x + 35
48(2) + 35 =96 + 35 =131
The value of 48x + 35 = 131 when x =2
147 ≠ 131
Therefore the two expressions are not equivalent when x = 2
