Answer:
Fraction form: -1/2
Decimal form: -0.5
Step-by-step explanation:
1: Subtract 7 from both sides
7 - 6x = 9 - 2x
7 - 7 - 6x = 9 - 7 - 2x
6x = 2 - 2x
2: Add 2x on both sides
6x + 2x = 2 - 2x + 2x
-4x = 2
3: Divide both sides by -4 to get x by itself
-4x/-4 = 2/-4
x = -1/2
(Which can also be written as -0.5 in decimal form )
