A number=x
2x/6=42
2x=252 by multiplying both sides by 6
x=126 by dividing both sides by 2 to isolate the variable
Answer:
x= 120
Step-by-step explanation:
x+60=180
x=180-60
x=120
Answer:
(1,2)
y=2
x=1
Step-by-step explanation:
x+y=3
3x+5y=13
solve the equation
x=3-y
3x+5y=13
substitute the value of x into an equation
3(3-y)+5y=13
distribute
9-3y+5y=13
add -3y to 5y
9+2y=13
subtract 9 from both sides
2y=4
divide both sides by 2
y=2
substitute the value of y into an equation
x=3-2
subtract 3 to 2
x=1

Bill's Statement is Sometimes true.
Bill's statement is only true if 1 or both of the variables are positive but if both r and s are negative then it will be located on the left of r. Ex. r=-1 s=-2 (-1)+(-2)=-3
