I am pretty sure you subtract but in case it would be
(23,43) - (17,14).
(6,19) should be the answer
Answer:
c=-5
Step-by-step explanation:
2c-3=12-2c+7c
2c-3=12+5c
2c-5c-3=12
-3c-3=12
-3c=12+3
-3c=15
c=15/-3
c=-5
(2x+1) (x+7)
I solved it by using the FOIL method, but you get the same answer either way
Step 1: Simplify both sides of the equation.
x−7=15+3x
x+−7=15+3x
x−7=3x+15
Step 2: Subtract 3x from both sides.
x−7−3x=3x+15−3x
−2x−7=15
Step 3: Add 7 to both sides.
−2x−7+7=15+7
−2x=22
Step 4: Divide both sides by -2.
−2x/−2=22/−2
x=−11
