Answer:

x = -3/2 or -1.5

Step-by-step explanation:

You have to get X on one side by itself.

2x + 4 - 7x + 9x = -2

Subtract the 4

2x - 7x + 9x = -6

Combine like terms

-5x + 9x = -6

Combine like terms

4x = -6

Divide by 4

x = -6/4

Simplify

x = -3/2 or -1.5

The ratio between the number of children (c) on a field trip and number of teachers (t) on the trips is 14/3. There are 70 child

Mrrafil [7]

For this case we have a relationship of the form:
$c / t = 14/3
$
There are 70 children on the field trip
Therefore, we must replace the value of c = 70 in the equation.
We have then:
$70 / t = 14/3
$
Clearing t, we have:
$t = (3/14) * (70)

t = 15$
Answer:
there are 15 teachers on the trip
