Answer:
A. 8x10^7 is 4000 times larger tham 2x10^4
Step-by-step explanation:
Answer:
No solutions
Step-by-step explanation:
i did this via substitution so i hope it isn't a problem
3x+y=4
6x+2y=−4
Step: Solve 3x+y=4for y:
3x+y+−3x=4+−3x(Add -3x to both sides)
y=−3x+4
Step: Substitute−3x+4foryin6x+2y=−4:
6x+2y=−4
6x+2(−3x+4)=−4
8=−4(Simplify both sides of the equation)
8+−8=−4+−8(Add -8 to both sides)
0=−12
so there are no solutions
hope this helps!!
Okay so plug them in to get x and y so use 5 as x and 1 as y
E,D and B are all the correct choices that are equivalent to 3(4x+3)
