Answer:

= - 2/7 - 2√5

= - 2/7 - 2√5 x 7 + 2√5/7 + 2√5

= - 14 - 4√5/49 + 14√5 - 14√5 - 20

= - 14 - 4√5/ 29

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
