Determine whether (-2,-1) is solution of 7x+6y=-3
Substitute (-2,-1), i.e. x=-2, y=-1, into 7x+6y=-3 and see if the two sides of the equation are equal. If so, (-2,-1) is a point that is on the line. If not, the given line (equation) does not pass through the given point.
8x=-72
i divided on each side and my answer is x=-9 i'm i right
by the way thanks
To determine whether (-2,-1) is a solution of the equation 7x + 6y = -3, you need to substitute the values of x and y into the equation and see if both sides are equal.
Step-by-step solution:
Step 1: Substitute the values of x and y into the equation:
7(-2) + 6(-1) = -3
Step 2: Simplify both sides of the equation:
-14 - 6 = -3
-20 = -3
Step 3: Determine if both sides of the equation are equal:
Since -20 does not equal -3, we can conclude that (-2, -1) is not a solution of the equation 7x + 6y = -3.
Therefore, (-2, -1) is not a solution of the equation 7x + 6y = -3.
