WebProblem 1 in practice is: (3/2)y-3+ (5/3)z given the values of y=4 and z=3 Substitute the vales for the variables: (3/2) (4/1)-3+ (5/3) (3/1) Follow PEMDAS rules. Multiply first. (3/2) (4/1)=12/2=6 (5/3) (3/1)=15/3=5 So, the expression is now: 6-3+5 Now, add and subtract from left to right. 6-3+5 = 3+5 = 8 The answer is 8. WebHow to evaluate an expression with one variable Let's say we want to evaluate the expression a + 4 a+4. Well, first we need to know the value of the variable a a.
