Question

Find the value of expressions if, x= 2 and y =5 9y + x/2 please answer
​

Answer 1

How do I evaluate the expression?

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expressionHow do you find the value of X and Y in two equations?

If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value

Answer 2

$9y= \frac{x}{2}$

$9 \times 5 = \frac{2}{2}$

$45 \times 2 = 2$

$90≠2$
