Step-by-step explanation:
73.
18 = 3x[tex]\sqrt{3}[/tex] (divide both sides by 3 )
6 = x[tex]\sqrt{3}[/tex] ( multiply both sides by [tex]\sqrt{3}[/tex] )
6[tex]\sqrt{3}[/tex] = 3x [ [tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] = 3 ]
divide both sides by 3
x = 2[tex]\sqrt{3}[/tex]
74.
24 = 2x[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
12 = x[tex]\sqrt{2}[/tex] ( multiply both sides by [tex]\sqrt{2}[/tex] )
12[tex]\sqrt{2}[/tex] = 2x ( divide both sides by 2 )
x = 6[tex]\sqrt{2}[/tex]
75.
9[tex]\sqrt{2}[/tex] × x = 18[tex]\sqrt{2}[/tex] ( divide both sides by 9[tex]\sqrt{2}[/tex] )
x = 2
76.
2 = x × [tex]\frac{4}{\sqrt{3} }[/tex] ( multiply both sides by [tex]\sqrt{3}[/tex] )
2[tex]\sqrt{3}[/tex] = 4x ( divide both sides by 4 )
x = [tex]\frac{\sqrt{3} }{2}[/tex]
