Answer 1

x = -14/5

or

-2.8

Explanation:

7x+5=2x-9

What’s the value of x?

7x + 5 = 2x - 9

7x - 2x = -9 -5

5x = -14

x = - 14 : 5

x = -14/5 or -2.8

------------------------------------

check

7× (-14/5) + 5 = 2 × (-14/5) - 9

-19.6 + 5 = -5.6 - 9

-14.6 = -14.6

same result the answer is good
