I dont see the question :/
Step-by-step explanation:
Answer:
if we subtract both sides by 3x, then we will have 8 = -5 which is a mathmatical contradiciton
Answer:
x=12 y=9
Step-by-step explanation:
first we need to do this equation to get X
we don't have y so y=0
x-(0)=12
we eliminate the 0
x=12
now, we have X, now we need to find Y
substitution
x+y=3
12+y=3
y=3-12
y= 9
The distributive property is multiplying the numbers outside of the parentheses into the inside
2×4x=8x
2×3=6
8x+6+4
Then do the same thing on the other side
Which gets you
3x-2x-4
so he has the equation
8x+6+4=3x-2x-4
so the answer is B
