Answer:
<h3>The answer is 243.</h3>
Step-by-step explanation:
To evaluate the expression substitute the values of a , b , c and d into the above expression
a = - 9
b = - 7
c = 9
d = 3
So we have
2cd + 3ab = 2(9)(3) + 3(-9)(-7)
= 2(27) + 3( 63)
= 54 + 189
We have the final answer as

Here are the answers for 10 and 12
-5 +y = -23
add 5 to each side
y = -18
-3x+6y = -3
-3x + 6(-18) = -3
-3x -108 = -3
add108 to each side
-3x = 105
divide by -3
x = -35
x=-35
y= -18
