To solve the equation, first use the distributive property as follows:
3(-2x + 4) = 7x - 23
-6x + 12 = 7x- 23
Now use inverse operations to solve for as follows:
-6x + 12 = 7x- 23
-6x + 12 + 6x = 7x - 23 + 6x
12 = 13x - 23
12 + 23 = 13x - 23 + 23
35 = 13x
35/13 = 13x/13
35/13 = x
35/13 in decimal form is 2.692 as well.
