An equation is formed of two equal expressions. The value of x in the solution of the system of equations is 4.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the two of the system of equations 5x + 4y = 8 and 2x − 3y = 17. The solution of the system of equation is,
Solve the first equation for y,
5x + 4y = 8
4y = 8 - 5x
y = (8-5x)/4
Substitute the value of y in the second equation,
2x − 3y = 17
\(2x - \dfrac{3(8-5x)}{4} = 17\)
8x - 24 +15x = 68
23x = 92
x = 4
Hence, the value of x in the solution of the system of equations is 4.
