Answer = $44
1. Divide $140 by 5/7. It will give us how much Kelvin had originally, which is $196
(I got 5/7 by doing 7/7 - 2/7)
2. Find 2/7 of 196 by multiplying them. This is 56....meaning that Kelvin gave James $56
3. Subtract 100 - 56 to find how much James had before this, which is $44.
Y-5=3-9(y+2). so so u are going to distribute-9 to y and 2 which is -9y-18
so u are going to add like terms 3 and -18 which is -15. so the next step is going to be y-5=-9y-15 so u are going to add 5 to -5 and -15 to balance the equation and u will get -10 . y=-9y -10. since u are multiplying -9 by y so have to expand it y= -9 * y -10. so u have to divide y by y to get y . -9-10= -19 soo y =-19
X=3
2+10+3=35
I got 35 beacsue it's and estiment off of 40
2x-1=7x+44 is equal to -9. The first step is to add one on both sides to get x by itself. Right now you should have 2x= 7x+45. Then you subtract 7x from both sides. You should have -5x=45. Now divided -5 on both sides. You should get the answer x=-9. By the way remember only subtract variables from other variable and regular numbers only from other regular numbers. Hope this helps, if you have any questions please comment.
