2(1/4x + 4) = 3(x -2) PLZ HELP
frozen [14]
Distribute 2 and remove parentheses :
1/2x+8=3x-6
Multiply both sides of equation by 2:
x+16=6x-12
Move terms:
x+16-6x=-12
x-6x=-12-16
Collect like terms:
-5x=-28
Divide both sides:
x=28/5

For 2< it’ll have to be something greater that two or 2 and then for <5 it’ll be the same so for example if it was like that I’ll do it like this: 3x5=15
