6c+14=−5c+4+9c What does C equal?

maria [59]

Answer: c = -5

Step-by-step explanation:

$6c+14=-5c+4+9c$

Combine like terms

$6c+14=4c+4$

Subtract 4c from both sides.

$-4c+6c+14=4c+4-4c\\2c+14=4$

Subtract 14 from both sides.

$2c+14-14=4-14\\2c=-10\\$

Divide by 2 to isolate c

$\frac{2c}{2}=\frac{-10}{2}\\ c=-5$

Check:

$6c+14=-5c+4+9c\\6(-5)+14=-5(-5)+4+9(-5)\\-30+14=25+4-45\\-16=29-45\\-16=-16$

Find the solution of this system of equations.

Elenna [48]

-4x + y = -25 y = 4x - 25

-6x - 6y = 0 

-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5

y = 4(5) - 25
y = 20 - 25
y = -5

(5, -5)
