First write it to equal 0,

(65x-12) + (43x + 10) = 0

Now you want all the x’s to be on one side and the constants on the other. So move one of them by doing the opposite. I will be moving the constants over

65x + 43x = -10 + 12

(subtract 10 add add 12 because they're opposite factors)

Now you can add like terms (65x + 43x) and -10 and 12

108 = 2

Now be because 108 is essentially a multiplication, you need to divide by 108 so it will just equal x

X = 2/108

And like any fraction you can simplify it to

X = 1/54
