Question

how do you solve a equation like this 7/8 + X=4

Answer 1

To isolate a variable (f.e. X):

subtract, add, multiply and/or divide to get numbers on one side and variables on the other side

Answer 2

You want to solve for x, right?

Answer 3

yah

Answer 4

x = 4 - (7/8)

Answer 5

Okay, so like @Tajar said, you need the x alone on one side of the equation. This one is pretty simple. All you gotta do is move 7/8 to the other side. Since you're moving it to the opposite side of the equal sign, you need to make 7/8 negative. So you'd have x = 4 - 7/8.
Get it? Think you can take it from there? =)
