What is the answer to 1.1x + 1.2x - 5.4 = -10
2 answers:
1.1x+1.2x-5.4=-10
11/10x+12/10x-54/10=10
11x/2.5+2^2-1*3/5x-3^3/5=-10
(11x)+2(2*3x)+2(-3^3)/2*5=-10
11x+2(6x)+2(-27)/2*5=-10
11x+2*6x-2*27/2*5=-10
11x+12x-54/2*5=-10
23x-54/2*5=-10
23x-54=-100
23x=-46
23x/23=-46/23
x=-2*23/23
x=-2
PEMDAS
1.1x + 1.2x = 2.3x
-10 + 5.4 = -4.6
-4.6/2.3 = -2
