Answer:
5
Step-by-step explanation:
You have to move all variables to the left side of the equation. It should be
5c-7c=-2-8. Notice how when 7c and 8 get moved over to their designated places, they become a negative. 5c-7c equals to -2c. -2-8 equals to -10. The equation we have now is -2c=-10. 10 divided by 2 is 5 and there ar two negatives which equal a postiive so the answer is 5.
Answer:
[tex]\boxed {c = 5}[/tex]
Step-by-step explanation:
Solve for the value of [tex]c[/tex]:
[tex]8 + 5c = 7c - 2[/tex]
-Take [tex]7c[/tex] and subtract it from [tex]5c[/tex]:
[tex]8 + 5c - 7c = 7c - 7c - 2[/tex]
[tex]8 - 2c = -2[/tex]
-Subtract [tex]8[/tex] to both sides:
[tex]8 - 8 - 2c = -2 - 8[/tex]
[tex]-2c = -10[/tex]
-Divide both sides by [tex]-2[/tex]:
[tex]\frac{-2c}{-2} = \frac{-10}{-2}[/tex]
[tex]\boxed {c = 5}[/tex]
Therefore, the value of [tex]c[/tex] is [tex]5[/tex].
