4x - .5 = 8
Add 0.5 to both sides: 4x = 8.5
divide both sides by 4: x = 2.125

is it 8
3/4x5/2= 3x5=15 over 2x4=8 = 15/8 = 1and 7/8.
Assume that the expression 4x5 in the question is 4x5.4x5 = 3 : x5 = 3/4 : x = 5√(3/4) : then 2k.5√(3/4) + 10 = 2 : 2k.5√(3/4) = 2 - 10 = -8 :k = -4 ÷ 5√(3/4) = -4 ÷ 0.9441 = -4.2369 (4dp)
