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. For example, to evaluate the expression when \blueD {a = 1} a = 1, we just replace \blueD a a with \blueD 1 1:

WebMar 4, 2024 · Following “Tips for Evaluating Algebraic Expressions,” first replace all occurrences of variables in the expression ( a − b) 2 with open parentheses. (a − b)2 = (() − ())2 Secondly, replace each variable with its given value, and thirdly, follow the “Rules Guiding Order of Operations” to evaluate the resulting expression. Mar 4, 2011 · WebTo evaluate an algebraic expression for a given value, you have to substitute the variable of the expression for the value and perform all the arithmetic operations of the expression. For example, to evaluate the expression 3x+5 for x=1, you have to replace the variable x with the number 1 and perform the calculations: 3 (1)+5=8. cabcharge taxi vouchers
