Given the expression:
a x 3 = -30
-9 x b = 45
Let's determine the value of each variable.
At a x 3 = -30,
[tex]\text{ a x 3 = -30}[/tex][tex]3a\text{ = -30}[/tex][tex]\frac{3a}{3}=\text{ }\frac{\text{-30}}{3}[/tex][tex]\text{ a = -10}[/tex]At -9 x b = 45,
[tex]-9\text{ x b = 45}[/tex][tex]-9b\text{ = 45}[/tex][tex]\frac{-9b}{-9}=\frac{45}{-9}[/tex][tex]b=\text{ -5}[/tex]Therefore, a = -10 and b = -5.
