Answer:
Step-by-step explanation:
1) 9 x 4 = 36
9 + 4 = 13
2) 9 x -4 = -36
9 + (-4) = 5
3) 4 x3 = 12
4+ 3 = 7
4) -4 x 3 = -12
-4 + 3 = -1
Answer:
x=-8
Step-by-step explanation:
First you should add 5x+67 and 5x+61 together which is 10x+128
Then you set that equal to 3x+72 which would be: 10x+128=3x+72
After that subtract 3x from both sides which leaves you with: 7x+128=72
Then subtract 128 from 72 which gives you: 7x=-56
Then divide by 7 which gives you x equals negative eight
