Explanation:
<span>5a−10b=45</span> , when <span>b=3</span>
Substitute the value of b into the equation.
<span>5a−10<span>(3)</span>=45</span>
Solve for a.
<span>5a−10<span>(3)</span>=45</span>
<span>5a−30=45</span>
<span>5a=75</span>

Step-by-step explanation:
strange, because the way you typed it, it would be absolutely correct.
If a < b and if c is a positive number, then
a/c < b/c
Dividing each side of an inequality by a positive number does not change the direction of the inequality symbol.
that is one of the defined rules.
so, did you make a mistake with a sign ? maybe the division is meant to be by -3 ?
then indeed, suddenly
5 > 2
so, please check the problem definition precisely. if your correct answer is actually wrong, then the original problem must be different than what you typed here.
