Question

Solve the equations for x and match the solutions.

Answer 1

Answer:

Step-by-step explanation:

by putting 4=6/ax+5

Answer 2

Answer:

1. The solution of first equation is $x=-\frac{a}{6}$.

2. Therefore the solution of second equation is $x=\frac{3}{a}$.

3. The solution of third equation is $x=-\frac{6}{a}$.

Step-by-step explanation:

The first equation is

$4=\frac{6}{a}x+5$

Subtract 5 from both the sides.

$4-5=\frac{6}{a}x+5-5$

$-1=\frac{6}{a}x$

Multiply both sides by a.

$-a=6x$

Divide both sides by 6.

$-\frac{a}{6}=x$

Therefore the solution of first equation is $x=-\frac{a}{6}$.

The second equation is

$7+2ax=13$

Subtract 7 from both the sides.

$7+2ax-7=13-7$

$2ax=6$

Multiply both sides by 2a.

$\frac{2ax}{2a}=\frac{6}{2a}$

$x=\frac{3}{a}$

Therefore the solution of second equation is $x=\frac{3}{a}$.

The third equation is

$-ax-20=-14$

Add 20 on both the sides.

$-ax-20+20=-14+20$

$-ax=6$

Multiply both sides by -a.

$x=-\frac{6}{a}$

Therefore the solution of third equation is $x=-\frac{6}{a}$.
