Final answer:
To evaluate 3x + 4y - 6 when x=10 and y=2, substitute the values into the expression and simplify to get the result, which is 32.
Step-by-step explanation:
To evaluate the expression 3x + 4y - 6 when x=10 and y=2, we substitute these values into the expression and perform the calculations.
Step 1: Substitute x = 10 and y = 2 into the expression.
3(10) + 4(2) - 6
Step 2: Multiply the coefficients by their respective variables.
30 + 8 - 6
Step 3: Add and subtract the numbers.
30 + 8 = 38
38 - 6 = 32
Therefore, the value of the expression when x = 10 and y = 2 is 32.
Equations are mathematical statements that assert the equality of two expressions. They typically contain variables, constants, and mathematical operations like addition, subtraction, multiplication, division, exponents, and more. Equations are solved to find the value(s) of the variables that satisfy the equality.
