3 x 5 - 12
15 - 12
3
Step-by-step explanation:
PEMDAS. do what is in parenthesis first, then divide/multiply, reading from left to right, then add/subtract reading from left to right.
4x=5x-12
subtract 5x from each side
-x=-12
to get a positive x multiply each side by a -1
x=12
Hope I helped :)
The answer would be a. 9/10 after simplifying 18/20 which is what you get after getting your common denominator.
X+y=12
x-2y=6
hmm
multiply 2nd equation by -1 and add to first
-x+2y=-6
<u>x+y=12 +</u>
0x+3y=6
3y=6
y=2
sub back
x+y=12
x+2=12
x=10
x=10, y=2
