Question

9у+2(6у+5)при у =7 ​

Answer 1

9*7+2*42+10=63+84+10=157

Answer 2

To evaluate the expression 9у + 2(6у + 5) when у = 7, we simply substitute the value of у into the expression and perform the calculations. Let's do that step by step:

1. Replace у with 7: 9(7) + 2(6(7) + 5)

2. Perform the innermost calculations first: 9(7) + 2(42 + 5)

3. Continue with the innermost parentheses: 9(7) + 2(47)

4. Perform the multiplication: 63 + 94

5. Finally, add the two values: 157

So, when у = 7, the expression 9у + 2(6у + 5) evaluates to 157.
