The value of h will be 26, when p =7.
What is linear equation in two variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.
What is substitution method?
The method in which, the value of one variable from one equation is substituted in the other equation. So that, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. This method is called substitution method.
According to the given question we have
A linear equation in two variable
h = 3p + 5
So, the value of h when p = 7
Substitute, p = 7 in h = 3p + 5
⇒ h = (3 × 7) + 5
⇒ h = 21 + 5
⇒ h = 26
Hence, the value of h will be 26, when p =7.
