what numbers x and f
2%28F%2B8%29-3x=-12
2%28F%2B8%29-3x=-12
2F%2B16-3x=-12
solve for x:
2F%2B16+%2B12=+3x...divide both sides by 3
2F%2F3%2B16%2F3+%2B12%2F3=+3x%2F3
+%282%2F3%29F+%2B+5.33+%2B+4=+x
x+=%282%2F3%29F+%2B+9.33

solve for F:
2F%2B16+%2B12=+3x...
2F=+3x+-16+-12...divide both sides by 2
2F%2F2=+3x%2F2+-16%2F2+-12%2F2...
F=+%283%2F2%29x+-8+-6...
F=+%283%2F2%29x+-14...
