None of the above. Because your expression would be, 2 + 0.75 x 6.
Hope it helps. ;)
8.6*7=60.2, 16*1.4=22.4, 12*14=168, 7.3*20=146
6x+4/5=8
subtract 6x from both sides
4/5=8-6x
multiply both sides by 5 to get rid of the fraction
4=40-30x
divide both sides by 2
2=20-15x
add 15x to both sides
15x+2=20
subtract 2 from both sides
15x=18
divide both sides by 15
x=1.2
