Answer: x= -2, c= -8
Step-by-step explanation: To solve the first equation, move the 12 over to the right side. To do this, do the oposite operation. So add 12 on both sides. The 12 on the left side cancels out, and you are left with x= -14+12. X=-2. Do the same thing for the next equation. Subtract 7 from the left side and the right side. C= -1-7. C= -8
Answer: D 5x=30
Step-by-step explanation
You just substitute 6 into the equations to see if they make the equation true.
A=2(L+W) A=2L+2W A-2L=2L-2L+2W A-2L=2W A-2L divided by 2=2W/2 A-2L divided by 2=W
