Step-by-step explanation:
8y- 8
[tex]8 \times 2 - 8[/tex]
[tex]16 - 8[/tex]
[tex]8[/tex]
The value of the expression 8y - 8 when y = 2 is 8.
Given,
8y - 8
We need to find the value of the expression 8y - 8 when y is 2.
It depends on the types of the equation given.
We can use the PEMDAS order where
P - Parenthesis
E - exponents
M - multiplication
D - division
A - addition
S - subtraction
We can also find by substituting the value of a variable if the value of the variable is given.
For example:
ax + b at x = 2
ax2 + b = 2a + b is our answer
We have,
8y - 8
Putting y = 2 in 8y - 8.
= 8y - 8
= 8 x 2 - 8
= 16 - 8
= 8
Thus the value of the expression 8y - 8 when y = 2 is 8.
