Solve the two-step equation.-0.45x + 0.33 = -0.66What is the solution?x = -2.2x = -1.4x = 1.4x = 2.2f

Softa [21]

Answer:

x = 2.2

Step-by-step explanation:

-0.45x + 0.33 = -0.66

Subtract .33 from each side

-0.45x + 0.33-.33 = -0.66-.33

-.45x = -.99

Divide each side by -.45

-.45x./-.45 = -.99/-.45

x = 11/5

x = 2.2

zubka84 [21]

Use distributive property to solve.
2x(5x+3) + 7(5x+3)
1. distribute

2x•5x = 10x^2
2x•3= 6x

10x^2+6x

7•5x = 35x
7•3= 21

35x+21

2. combine like terms

10x^2+6x+35x+21

10x^+ 41x +21 [final answer]
