Answer and explanation
Correct answer: 11
Given \(x=2\), substitute it in \(4x+3\): \(4(2)+3=8+3=11\). Therefore, the correct answer is 11. The value 8 is only \(4\times2\); the additional 3 must still be added. Exam tip: Substitute the value of the variable first, then follow the order of operations.
