Answer:

Step-by-step explanation:

Since they are similar we can say

(7x-13)/42=(x+5)/14 upon cross multiplication we have

14(7x-13)=42(x+5) divide each side by 14

7x-13=3(x+5) expanding right side

7x-13=3x+15 adding 13 to each side

7x=3x+28 subtracting 3x from each side

4x=28 dividing each side by 4

x=7

How many solutions do you think the equation -10x+3=5x-27 has? Explain. Then, find the solution(s).
deff fn [24]
This will only have one solution because it does not deal with a quadratic. Then to isolate x you need to get the similar terms on different sides by subtracting or adding, Then divide both sides by the number next to x (coefficient).
