Solve the following: -7x + 5 = 8x - 25

explain you < 3

x = 2

Step-by-step explanation:

Reorder the terms:

-5 + 7x = 25 + -8x

Add '8x' to each side of the equation:

-5 + (7x + 8x) = 25 + (-8x + 8x)

Combine like terms: 7x + 8x = 15x :

-5 + 15x = 25 + -8x + 8x

Combine like terms: -8x + 8x = 0

-5 + 15x = 25 + 0

-5 + 15x = 25

Combine like terms: 25 + 5 = 30 :

15x = 30

Divide each side by '15':

x = 2

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
