Can someone help me x-7=2x-6
2 answers:
X=-1
x-7=2x-6
subtract x from both sides.
-7=x-6
add 6 on both sides.
X - 7 = 2x - 6 Add 6 to both sides
x - 1 = 2x Subtract x from both sides
-1 = x Flip it around so it's easier to read
x = -1
Check your answer by substituting -1 in for x.
(-1) - 7 = 2(-1) - 6 Simplify 2 times -1
(-1) - 7 = -2 - 6 Simplify both sides
-8 = -8
So, x = -1 .
