7c+ 12= -4c+ 78
⇒ 7c+ 4c= 78 -12 (inverse operation)
⇒ 11c= 66
⇒ c= 66/11 (inverse operation)
⇒ c= 6
Final answer: c= 6.
Answer:
-12
Step-by-step explanation:
To evaluate the expression the known value of a = -8 can be substituted in so the equation becomes -8 - 4.
From there the subtraction can be completed which equals -12. This can be visually seen on a number line if you look at -8 and move left 4 spaces.
Answer:
(6m+6)
Now you factor out the common term 6 and get
6(m + 1)
