Answer:
I. x = -3
II. y = -2
Explanation:
Given the following algebraic equation;
.........equation 1
..........equation 2
We would solve the algebraic equation using the substitution method
From equation 1;
.....equation 3
Substituting eqn 3 into eqn 2, we have;
Multiplying all through by 5
Rearranging the equation, we have:
x = -3
Next we find the value of y;
From eqn 3;
Substituting the value of "x" into the equation, we have;
y = -2
