Question

Medal to check my work:

Melinda starts with $22 and saves $10 each week. George starts with $10 and saves $13 each week.

After how many weeks will they have the same amount saved?
22 + (10 * x) = 10 + (13 * x)
-10 -10
=12
12 + (10 * x) = 13 * x
-12 -12
=1
10x = 1x
/1 /1
10 = x?
Correct? Probably not, will someone help me?

Answer 1

22 + 10 * 10 = 10 + 13 * 10
100 130
22 + 100 = 10 + 130
122 = 140 not correct

Answer 2

This part is not right
12 + (10 * x) = 13 * x
-12 -12
=1
Can't subtract 12 from the coefficient of x

Answer 3

in the second step you should subtract 10x , instead of 12

Answer 4

12 + 10x = 13x
/10 /10
=1.3
12 = 1.3x
/1.3 /1.3
9.23076923077 = x?

or are you suppose to subtract 1.3?
12 = 1.3x
-1.3 -1.3
10.7 = x???

Answer 5

wait your suppose to subtract 10?

Answer 6

12 +10x = 13x
-10 -10
3x
12 = 3x
3 3
4 = x

Answer 7

@aleroth @b87lar

Answer 8

That's not right either, you want to get all numbers with x on one side and all 'lonely' numbers on the other side

Answer 9

What b87lar meant was to subtract 10x on both sides

Answer 10

i did that

Answer 11

Oops, sorry I didn't see the last thing there. Yeah, that's right!! D:

Answer 12
