Answer:
to 1dp = -2.6
to 2 dp= -2.64
as fraction = 29/-11
Explanation:
x+1 = 6(2x+5) - you multiply each side by 2x + 5
x+1 =12x+30 - expanding the brackets
x-12x+1=30 - subtract 12x from both sides
x -12x = 30-1 - subtract one from both sides
-11x = 29 - you just work each side out to get these answers
29/-11 =x - divide -11 from both sides
-2.63636363636 =x - using a calculator ( if finding whole number ) you do 29/-11
to 1dp = -2.6
to 2 dp= -2.64
