Answer 1

1) $a= -1$,  2) $n=-2$

3) $x=4$,   4) $n=0$

5) $r=1$,     6) $r=2$

7) $No\,\,solution$,     8) $p=-12$

9) $m=2$,    10) $a=-3$

11) $x=4$       12) $n=-2$

Step-by-step explanation:

We need to solve each equation.

1) $6a+5a = -11$

Solving:

Adding like terms:

$11a = -11$

Divide both sides by 11

$a= -1$

2) $-6n-2n=16$

Solving:

Adding like terms:

$-8n=16$

Divide by -8

$n=-2$

3) $4x+6+3=17$

Solving:

Adding like terms:

$4x+9=17$

Subtract 9 on both sides:

$4x=17-9$

$4x=8$

Divide both sides by 4

$x=4$

4) $0=-5n-2n$

Solving:

$0=-7n$

Divide both side by -7

$n=0$

5) $6r-1+6r=11$

Solving:

12r-1=11

Adding 1 on both sides

$12r=12$

Divide both sides by 12

$r=1$

6) $r+11+8r=29$

Solving:

$9r+11=29\\9r=29-11\\9r=18\\r=2$

7) $-10=-14v+14v$

Solving

$-10=-14v+14v\\-10\neq 0\\No\,\,solution$

8) $-10p+9p=12$

Solving:

$-10p+9p=12\\-p=12\\p=-12$

9) $42=8m+13m$

Solving:

$42=8m+13m\\42=21m\\m=42/21\\m=2$

10) $a-2+3=-2$

Solving:

$a-2+3=-2\\a+1=-2\\a=-2-1\\a=-3$

11) $18=3(3x-6)$

Solving:

$18=3(3x-6)\\18=9x-18\\18+18=9x\\36=9x\\x=36/9\\x=4$

12) $30=-5(6n+6)$

Solving:

$30=-5(6n+6)\\30=-30n-30\\30+30=-30n\\60=-30n\\n=60/-30\\n=-2$
