Can someone answer this?

Paha777 [63]

Answer:

x=1

Step-by-step explanation:

Convert decimals to fractions:

11/5x + 11/5 / 4= 1.1

Simplifies the fraction:

11x+11 / 20= 1.1

Remove denominator (then multiply by 20 on both sides):

11x+11=22

Move the x to the left:

11x= -11+22 → 11x=11

Simplify:

11x=11 → x=1
