Substitute y for -2 so 4x-3(-2)= 18, which -3 * -2 is +6 so then it'd be 4x + 6 = 18, then subtract 6 so 4x = 12, then divide by 4 so x = 3. dont forget that in match the positive&negative signs count.

Hey there!☺

$Answer:\boxed{683\frac{13}{20}}$

$Explanation:$

$594\frac{7}{25}+89\frac{37}{100}$

To solve, we will need to evaluate:

$594\frac{7}{25}+89\frac{37}{100}=\frac{13673}{20}$
