Question

What is the solution to this equation? 7x + 3 = 10x - 5.4

Answer 1

Answer:

$x=2.8$

Step-by-step explanation:

$7x+3=10x-5.4$

Subtract 3 from both sides:

$7x+3-3=10x-5.4-3$

$7x=10x-8.4$

Subtract 10x from both sides:

$7x-10x=10x-8.4-10x$

$-3x=-8.4$

Divide both sides by -3:

$\frac{-3x}{-3}=\frac{-8.4}{-3}$

$x=2.8$
