Answer:
x = -1/10 or -0.1
Step-by-step explanation:
-1.8 - 6x = 6(0.1 + 3x)
-1.8 - 6x = 0.6 + 18x
-6x - 18x = 0.6 + 1.8
-24x = 2.4
-x = 2.4/24
-x = 24/10 / 24
-x = 24/10 * 1/24
-x = 24/240
-x = 1/10
x = -0.1
-0.13
Expand the bracket
-1.8 - 6x = 6x0.1 + 6 x 2x
-1.8 -6x = 0.6 + 12x
Collect like terms
-1.8 -0.6 = 6x + 12x
-2.4 = 18x
Divide both sides by 18
-2.4/18 = 18x/18
x = -0.13
