Question

0.5(x - 4.0)/3.5 - 0.6(x - 2.71)/4.2 = x + 6.1​

Answer 1

Step-by-step explanation:

0.5x-2/3.5-0.6x-1.626/4.2=x+6.1

(0.5x-2)(-0.6x-1.626)/3.5×4.2=x+6.1

-0.3x^2-0.813x+1.2x+3.252/14.7=x+6.1

-0.3x^2+0.387x+3.252=14.7(x+6.1)

-0.3x^2+0.387x+3.252=14.7x+89.67

-0.3x^2+0.387-14.7x=89.67-3.252

-0.3x^2-14.313x=86.428
