NDING THE VALUE OF AN ALGEBRAIC EXPRESSION
It values of literals are given, we can find the value of the algebraic expression
ample 12: Find the value of 2x + 3y + 1 if
Remember
x=3 and y = -2
Literals represent numbers
ution: 2x + 3y + 1 = 2 × x + 3 x y + 1
= 2 x 3 + 3x (-2) + 1 (We substitute x = 3 and y = -2
= 6 - 6 + 1
(We multiply and then add the term
= 0+1​
