Answer:
x=−y−1
Step-by-step explanation:
y=−x−1
Step 1: Flip the equation.
−x−1=y
Step 2: Add 1 to both sides.
−x−1+1=y+1
−x=y+1
Step 3: Divide both sides by -1.
−x
−1
=
y+1
−1
x=−y−1
21 is the opposite of -21
Answer:
x=16
Step-by-step explanation:
First, since a and b are parallel, infer that 4x and 60 can be added together to reach 124 (4x+60=124). Then, solve the equation.
4x+60=124
subtract 60 from both sides
4x=64
divide by four
x=16
Answer:
1 = 61
