The solution of the equation y=2.5x-1.5 at x = 7 is 16.
What is a linear equation?
A linear equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The equation is solved as:-
y=2.5x-1.5
Put x = 7 in the above equation and solve for y.
y = (2.5x7) - 1.5
Subtract 1.5 from 17.5 to get the solution.
y = 17.5 - 1.5
y = 16.
Hence, the solution of the equation is y = 16.
