7(n - 7) = 3(2n + 3)

bija089 [108]

Answer: n=58

Step-by-step explanation:

7(n-7)=3(2n+3)

We move all terms to the left:

7(n-7)-(3(2n+3))=0

We multiply parentheses

7n-(3(2n+3))-49=0

We calculate terms in parentheses: -(3(2n+3)), so:

3(2n+3)

We multiply parentheses

6n+9

Back to the equation:

-(6n+9)

We get rid of parentheses

7n-6n-9-49=0

We add all the numbers together, and all the variables

n-58=0

We move all terms containing n to the left, all other terms to the right

n=58

Serious I need your help plz

makkiz [27]

Greetings!

Solve for x.
$\frac{x+11}{8} =-3$
Multply both sides by 8 to get rid of the fraction.
$8(\frac{x+11}{8}) =8(-3)$
$x+11=-24$
Add -11 to both sides.
$(x+11)+(-11)=(-24)+(-11)$
The Answer Is:
$x=-35$

Hope this helps.
