bro pls help
Which equation is equivalent to w=x+y−z?(1 point)
The equation that is equivalent to w = x + y - z is w + z = x + y.
that isnt an option on my screen here are the options
z=x+y+w
z equals x plus y plus w
z=w−x−y
z equals w minus x minus y
z=(x+y)w
z equals Start Fraction left parenthesis x plus y right parenthesis over w End Fraction
z=x+y−w
Apologies for the confusion. From the provided options, the equation that is equivalent to w = x + y - z is z = x + y - w.
thank you
what about this
Manipulate the equation y=7x−12 so that it is written in terms of x. Which equation is equivalent to y=7x−12?(1 point)
Responses
x=(y−12)7
x equals Start Fraction left parenthesis y minus 12 right parenthesis over 7 End Fraction
x=(y7)+12
x equals left parenthesis Start Fraction y over 7 End Fraction right parenthesis plus 12
x=(y12)−7
x equals left parenthesis Start Fraction y over 12 End Fraction right parenthesis minus 7
x=(y+12)7
To manipulate the equation y = 7x - 12 so that it is written in terms of x, the correct equation would be x = (y + 12)/7.

Andrea is 6 years younger than Tony. In two years, Tony will be three times as old as Andrea. Let a be Tony’s current age. Which of these linear equations can be used to find Andrea’s and Tony’s current ages?(1 point)
3(a+2)=a−6+2
3 left parenthesis a plus 2 right parenthesis equals a minus 6 plus 2
a=3(a+2)
a equals 3 left parenthesis a plus 2 right parenthesis
a+2=3(a+6+2)
a plus 2 equals 3 left parenthesis a plus 6 plus 2 right parenthesis
a+2=3(a−6+2)
a plus 2 equals 3 left parenthesis a minus 6 plus 2 right parenthesis
The linear equation that can be used to find Andrea's and Tony's current ages is: a+2=3(a-6+2)
Look at the expression: −3(2x+7)
