Answer:
y=15
x=43
(any variable can be used, I used x and y to make it easier to show)
Step-by-step explanation:
x+y=58
x-y=28
get x by its self
x=58-y
then subsitute into the other equation
(58-y)-y=28
58-2y=28
-2y=-30
y=15
sub. again
x+15=58
x=43
the right answer is
x = 4 and x = –10
I just take the test and I got it right I hope yall get it right to
Answer:
x = 5.5
Step-by-step explanation:
- 6-(2x-4)+x = 6-2x+4+x = 10-x
- 3(x-4) = 3x-12
- Based on the 1st and the 2nd steps, 10-x=3x-12 --> 10+12=3x+x --> 22 = 4x --> x =22/4 = 5.5
