Solve the following system by the substitution method. Check the solution.
To solve the below equation using substitution method.
4x + 5y = 34 ….Eqn 1
x = y + 4 ….Eqn 2
Substituting x from equation 2 in the 1st equation. It gives
4(y + 4) + 5y = 34
4y + 16 + 5y = 34
9y + 16 = 34
9y = 34 – 16
y = 18/9
y = 3
To find the value of x substituting the value of y in the...
