y = 4, x = 6
2
3x-4x=12 that means -x equals 12 so x equals -12
Math equations have an equals sign such as: 7+5=12 or 9x6=47+7 Math expressions do not have a equals sign such as: 43-27 or 8x40
X equals -4 because if you pluged in 12 divided by -3 it equals -4.
It equals 5
Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
It probably means that one of the equations is a linear combination of the others/ To that extent, the system of equations is over-specified.
1 + 11 = 12
2
3x-4x=12 that means -x equals 12 so x equals -12
12/12 equals 1
It equals number in a a dozen. source:see how well you can do on a equations test
You substract 6 to -8 so its equal to y over 6 equal -2 and the you multiply -2 by 6! So the y equal -12...
Math equations have an equals sign such as: 7+5=12 or 9x6=47+7 Math expressions do not have a equals sign such as: 43-27 or 8x40
If 3y = 12, 2y = 8
y = 12. It's the transitive property. y = 12 = 3x.
X equals -4 because if you pluged in 12 divided by -3 it equals -4.
