X + 2y = 5 3x + 5y = 14 Solve the system of equations.
x +2y = 5 multiplie by -3 => -3x -6y = -15
3x +5y = 14
-3x -6y = -15
3x +5y = 14
------------------- assum the same terms
0 -y = -1
y = 1
x +2y = 5
x +2*1 = 5
x +2 = 5
x = 5 -2
x = 3
x = 3
y = 1
The solution of the system of equation is x = 3 and y = 1.
The relation between two variables is called a system of equations.
Given
The system of equations;
\(\rm x + 2y = 5 \\\\3x + 5y = 14\)
From equation 1
\(\rm x+2y=5\\\\x=5-2y\)
Substitute the values of x in equation 2
\(\rm 3x+5y=14\\\\3(5-2y)+5y=14\\\\15-6y+5y=14\\\\-y=14-15\\\\-y=-1\\\\y=1\)
Substitute the value of y in equation 1
\(\rm x+2y=5\\\\x+2(1)=5\\\\x+2=5\\\\x=5-2\\\\x=3\)
Hence, the solution of the system of equation is x = 3 and y = 1.
