Answer:
(c, d) = (25, 35)
Step-by-step explanation:
Multiply the first equation by 2.5 and subtract the second one:
2.5(c +d) -(2.5c +1.75d) = 2.5(60) -(123.75)
0.75d = 26.25 . . . . . . . . . simplify
26.25/0.75 = d = 35 . . . . divide by the coefficient of d
60 -d = c = 25 . . . . . . . . . use the first equation to find c
(c, d) = (25, 35)
X-3y=18
X always has a 1 in front of it so
1x-3y=18
-1x -1x You will have to get -3y by its self.
-3y=-1x + 18 when you move 1x over the = it turns into a -1x
/-3 /-3 /-3 divided everything by -3 to get y by its self
Y= 1/3 - 6 and that is you answer

Answer:
15 + x = 38
KEY:
<u>Increased = addition</u>
is= equals to
a number = put any random letter, or my choice is just using "x" so its just means a varaible
HOPE THIS HELPED!!!!! :D
Answer:
All real numbers are solutions.
Step-by-step explanation:
3x-7=3(x-3)+2
3x-7=3x-7
subtract 7 from both sides
3x=3x
subtract 3x from both sides
0=0
All real numbers are solutions.
