Question

How do you solve for x in `4y + 3x = 5`?

Answer 1

`x=(5-4y)/3`

Explanation:

When solving for a variable, we need to isolate it using operands.

Initial equation:
`\qquad 4y+3x=5`

Subtract `4y` on both sides
`\qquad 3x+4y-4y=5-4y`
`\qquad 3x=5-4y`

Divide (everything) by 3:
`\qquad x=(5-4y)/3`
