4(6c+5) - 2(3c - 5) = 120
ira [324]

Answer:

c=5

Step-by-step explanation:

Simplify both sides of the equation.

4(6c+5)−2(3c−5)=120

(4)(6c)+(4)(5)+(−2)(3c)+(−2)(−5)=120(Distribute)

24c+20+−6c+10=120

(24c+−6c)+(20+10)=120(Combine Like Terms)

18c+30=120

Subtract 30 from both sides.

18c+30−30=120−30

18c=90

Divide both sides by 18.

\frac{18c}{18}=\frac{90}{18}

c=5

hope this helps... :/

Hello everyone, i am very confused by this question:
Lesechka [4]

Answer:

Read the explanation down

Step-by-step explanation:

This is a linear equation, because the equation does not have any exponents. Graph it by putting the equation into either slope-intercept form y=mx+b or point-slope form y−y1=m(x−x1).

Isolate y by first adding 6x to each side:

9y=6x−18

Divide each side by 9:

y=23x−2

Now graph the line y=23x−2 by first plotting the y intercept at (0,−2), then connecting points with a slope of 23.

graph{2/3x-2 [-10, 10, -5, 5]}
