Question

How many solutions are there to the equation bellos
11x+25=7x+15

Answer 1

Since this is a first grade equation, there is only one solution (or maybe not)

Let's solve it.

Move unknown terms to the left of the equal with changed sign and known terms to the right of the equal, with changed sign.

11x-7x = 15-25

4x = -10

Since x is multiplied by 4, divide both terms for 4

4x/4 = -10/4

x = -10/4

Answer 2

There is only one solution to thus equation and it is as followed:

11x+25=7x+15
11x -7x = 15 -25
4x = - 10
x = -10/4
