What is the value of x in the equation 1.5(х + 4) — 3 = 4.5(х – 2)? a 3b 4c 5d 9

B.4

Step-by-step explanation:

1.5(x+4) - 3 = 4.5( x-2)open brackets on both sides

1.5 x +6 -3= 4.5x- 9collect like terms

3+9 = 4.5 x- 1.5x

12=3xdivide by 3 both sides to get x

12/3=x

x=4

Step-by-step explanation:

In a direct proportion, the ratio between matching quantities stays the same if they are divided. (They form equivalent fractions). In an indirect (or inverse) proportion, as one quantity increases, the other decreases.  In an inverse proportion, the product of the matching quantities stays the same.
