Answer:

[tex]x=2.8[/tex]

Step-by-step explanation:

[tex]7x+3=10x-5.4[/tex]

Subtract 3 from both sides:

[tex]7x+3-3=10x-5.4-3[/tex]

[tex]7x=10x-8.4[/tex]

Subtract 10x from both sides:

[tex]7x-10x=10x-8.4-10x[/tex]

[tex]-3x=-8.4[/tex]

Divide both sides by -3:

[tex]\frac{-3x}{-3}=\frac{-8.4}{-3}[/tex]

[tex]x=2.8[/tex]
