Question

4(6c+5) - 2(3c - 5) = 120

Answer 1

Answer:

$c=5$

Step-by-step explanation:

$4(6c+5)-2(3c-5)=120$

Use the distributive property to expand the equation:

$4(6c)+4(5)-2(3c)-2(-5)=120\\\\24c+20-6c+10=120$

Combine like terms to simplify the equation:

$24c-6c+20+10=120\\\\18c+30=120$

Subtract 30 from both sides:

$18c+30-30=120-30\\\\18c=90$

Isolate the variable c. Divide both sides by 18:

$\frac{18c}{18}=\frac{90}{18}\\\\ c=5$

So, c is equal to 5.
