Answer:

pls mark me a brainliest

let x represent the number

7(x) + 5 = 7 - x

so we now group like terms

7x + x = 7 - 5

8x = 2

we now divide through by 8

[tex] \frac{8x}{8} = \frac{2}{8} [/tex]

[tex]x = \frac{1}{4} [/tex]

the final answer for the number is 1/4

Hope this will help

Have a good day
