-3x-2y=-12 by substitution
Answer: x = 0.25, y = 5.625 or (, )
Step-by-step explanation:
To solve by substitution, we will first isolate one of the variables in one of the given equations.
-7x - 2y = -13 ➜ y = -3.5x + 6.5
Then, we will substitute this into the other given equation and solve for x.
-3x - 2y = -12
-3x - 2(-3.5x + 6.5) = -12
-3x + 7x - 13 = -12
4x = 1
x = 0.25
Lastly, we will substitute this value of x into the equation we solved for to find y.
y = -3.5x + 6.5
y = -3.5(0.25) + 6.5
y = 5.625
Answer:
1,3
Step-by-step explanation:
Answer:
x=-8, 8
Step-by-step explanation:
–|x| = –8
To solve this absolute value inequality we remove the negative sign on the left hand side
Divide both sides by
If then
