Question

X+a=3/4
How do I solve for x first then a

Answer 1

`x + a = (3)/(4) \\ x = (3)/(4) - a`

for a:

`a = (3)/(4) - x`

Answer 2

`\\ \sf \longmapsto x+a=(3)/(4)`

`\\ \sf \longmapsto x=(3)/(4)-a`

`\\ \sf \longmapsto x=(3-4a)/(4)`

And

`\\ \sf \longmapsto a=(3)/(4)-x`

`\\ \sf \longmapsto a=(3-4x)/(4)`
