Correct Answer : A
To solve the expression given 𝑋=4X=4 and 𝑌=6Y=6, substitute these values into the expression and simplify step by step.
The expression is:
(4𝑋+3𝑌−8)−3(2𝑋−𝑌+2)
Substitute 𝑋=4 and 𝑌=6:
(4⋅4+3⋅6−8)−3(2⋅4−6+2)
Calculate the inner values:
(16+18−8)−3(8−6+2)
(26)−3(4)
Now calculate further:
26−12
This simplifies to: 14
So, the correct answer is: 14
