Answer:
Is there a x somewhere or is that litteraly how the equation is?
If so, -7 multiplied by 2 is -14,
-1 times -7 is 7,
add it together and you get
-7=28,
you could add 7 to both sides or subtract 28 from both sides and you'll get either 0=35 or -35=0
which would make the solution false since both sides are not the same
Answer:
10x2y3 -4xy2
Step-by-step explanation:
Just take the like terms and separate them-
1) 4x2y3 - (-7x2y3)= 10x2y3
2)2xy2 - 6xy2= -4xy
3)-2y - (-2y)= 0y
Hope this helps :)
