(3x−9x)+(12+8)
Answer
−6x+20
Answer:
Step-by-step explanation:
a. 3-4x=-7-4x
3=-7. no solution
b. 15 - 2x = -7x
15 = -5x
x=-3. one solution
c. 7y-21=6y-21
y=0
1. -3x+4=-3x+7
4=7
2. 10+2x = 5x+2
8=3x
x=3/8
3. x+5=x+5

Answer:
<h2>x=2 y=6</h2>
Step-by-step explanation:
x+y= 8
there are lots of pairs
y= 2x+2
there are lots of possibilities
but if
x+y=8 when y= 2x+2
then you plot both of these lines on a graph
you can do this by replacing
x by other numbers in both of the equations
i have done this and i found out x=2 and y=6
