To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
Hey, the answer to ur question is 360degrees ...option(C.)
Try to subtitute y with 3x - 7
15x - 5y = 14
15x - 5(3x - 7) = 14
15x - 15x + 35 = 14
35 ≠ 14
