Hello from MrBillDoesMath!
Answer:
See Discussion below
Discussion:
8x - 8 = 7x + 4 => add 8 to both sides
8x - 8 +8 = 7x + 4 + 8 => as 4+8 = 12
8x = 7x + 12 => subtract 7x from each side
8x -7x = 7x -7x + 12 => 7x - 7x = 0, 8x - 7x = x
x = 0 + 12 = 12
Thank you,
MrB
Answer:
x = 12 Correct
Step-by-step explanation:
8x - 8 = 7x + 4
subtract variable 7x since its the smallest aswell as subtract variable 7x from 8x
we now have 1x - 8 = 4
to get rid of negative numbers we add, so add +8 to the -8 and the equals 4
we now have 1x=12
divide variable 1x by itself but only the number and the equals12
1x divided by 1 equals x and 12 divided by 1 equals 12
so your left with 12.
