8. solve the equation for x. 6.5 = $\frac{-2.8x + 13.78}{-1.8}$

Explanation:

Step1: Multiply both sides by -1.8

$6.5\times(-1.8)=-2.8x + 13.78$ $-11.7=-2.8x + 13.78$

Step2: Subtract 13.78 from both sides

$-11.7-13.78=-2.8x$ $-25.48=-2.8x$

Step3: Divide both sides by -2.8

$x=\frac{-25.48}{-2.8}$ $x = 9.1$

Answer:

$x = 9.1$
