explanation

The expression 4y – 20 +12y – 2 can be simplified before we substitute the value of the variable y. We first need to collect the like terms.

Step 1: Collect like terms.

4y – 20 +12y – 2 = (4 + 12)y – 20 – 2

= 16y – 22

Step 2: Substitute the value y = 11.

16y – 22 = 16 × 11 – 22

Step 3: Perform the multiplication.

16 × 11 – 22 = 176 – 22

Step 4: Find the difference.

176 – 22 = 154
