55>-7x + 6
Get -7x by itself
Subtract 6 from both sides
49>-7x
Divide by -7 (Remember to flip the inequality sign when dividing by negatives)
-7
Answer:
true
Step-by-step explanation:
4x + 5y = -13.
Substitute the point in
4(-2) + 5(-1) = -13
-8+-5 = -13
-13 = -13
This is true so the point is a solution
Answer:
35
Step-by-step explanation:
1/5x - 3 = 4
first move 3 to the other side with addition
1/5x = 7
then you can divide 7 by 1/5
7/1 • 5/1 (when dividing fractions the second one is always the opposite reciprocal)
=35/1 = 35
