substitute y = 3x-12 into -4x + 3y = -11
-4x +3 (3x-12) = -11
distribute
-4x +9x-36 = -11
combine like terms
5x - 36 = -11
add 36 to each side
5x = 25
divide each side by 4
x = 5
noe we need to find y
y = 3x -12
y = 3(5) -12
= 15 -12
y = 3
answer (5,3)
27.1739% percent. to find that, all you have to do is multiply 2.5x100. that equals 250. divide this by 9.2, and that is your answer
9-8=1+5=6-2=4
That's the only one I can think of right now lol.... Hoped it helps! <3
Answer:
Inconsistent
Step-by-step explanation:
We are given the equations;
0.3y=0.6x+0.3
1.2x+0.6=0.6y
Assuming we are required to determine whether the system of equations are consistent or inconsistent
We are going to use substitution
Making y the subject;
Equation 1: 0.3y=0.6x+0.3
Dividing both sides by 0.3
y = 2x + 1
Equation 2: 1.2x+0.6=0.6y
Dividing both sides by 0.6
y = 2x + 1
This means both equations are similar and we can't get a solution.
Therefore, the system of equations is inconsistent.
