Given:
y = -3x + 6
y = 9
Determine the solution.
Solution:
Substitute 9 in the value of y.
9 = -3x + 6
In order to determine the solution, we solve for the value of x. Start by transposing 6 on the other side of the equation. Note that when transposing a number, the sign changes.
-3x = 9 -6
-3x = 3
Divide both sides by -3 in order to get the value of x.
x = -1
Final answer:
x = -1
