➷ 847) You need to cross multiply

Multiply both sides by (x - 7) and 3

This is what you should get:

$3x- 42 = 2x - 14$

Now we just need to get like terms on the same side.

Add 42 to both sides and subtract 2x from both also

Now you get this:

$x = 28$

848) It's the same principle in this one too.

Multiply both sides by (x - 13) and 11

You should get:

$11x - 132 = 12x - 156$

Subtract 11x from both sides and add 156 also

Now you get:

$x = 24$

849) Multiply both sides by x

You should get:

$x - 12 = -4x$

Add 4x to both sides and add 12 also:

$5x = 12$

Divide both sides by 5

$x = 2.4$

850) Multiply both sides by x

You should get:

$x-12 = 4x$

Subtract x from both sides:

$3x = -12$

Divide both sides by 3:

$x=-4$

Answer 2

Answer:

the answers are below the solution.

Step-by-step explanation:

847.  x-14/x-7 = 2/3

cross multiply

3(x - 14) = 2(x - 7)

open the bracket

3x - 42 = 2x - 14

combine the like terms

3x - 2x = -14 +42

x = -28

848. x - 12/x - 13 = 12/11

cross multiply

11(x - 12) = 12(x - 13)

11x - 132 = 12x - 156

combine the like terms

11x - 12x = -156 +132

-x = -24

divide by -1

-x/-1 = -24/-1

x = 24

849. x - 12/x = -4

first make x - 12/x a single fraction

x-12/x = -4

cross multiply

x - 12 = -4x

combine the like terms

-12 = -4x - x

-12 = -5x

divide by -5

-12/-5 = -5x/-5

2.4 = x

x = 2.4

850. x - 12/x = 4

make x - 12/x a single fraction

x-12/x = 4

cross multiply

x - 12 =4x

combine the like terms

-12 = 4x - x

-12 = 3x

divide by 3

-12/3 = 3x/3

-4 = x

x = -4

I hope this will help
