Find the value of 3g - h when g = 4 and h = 5. - OCR - GCSE Maths - Question 8 - 2019 - Paper 1

To find the value of the expression $3g - h$, we need to substitute the values of $g$ and $h$ into the expression.

1. Substitute the value of $g$: $3g = 3 imes 4 = 12$

2. Substitute the value of $h$: Given $h = 5$, we then have:

3g - h = 12 - 5 = 7.

Therefore, the value of the expression is 7.
