Your answer would be:
6(2y+1)
P(x)=-15+7/4=-2
P(y)=12-4/4=2
P=(-2,2)
You divide by -7 on both sides then add three to both sides and the answer is -3
<span>See examples before for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2. my own words didnt get off google im a teacher</span>
Because the highest power is 2 the degree of the problem is 2
