1 - 5x + 7x is an expression, not an equation (no equals sign), so you cannot solve for x. You can, however simplify (combine like terms) and get 1 + 2x.

x = 4 You have to add the 8x and 7x to get 15x and then divide 60 by 15 to get x by itself.
What is the answer to 7x plus 3 equals 15x plus 9?
7x + 3 = 15x + 97x+3 = 15x+9 7x-15x = 9-3-8x = 6x = -6/8 => -3/4Explanation of working out the problem:7x+3=15x+9We want X's on one side and numbers on opposite side of Equal.When we move from one side to another, we also replace + with - and vice versa.7x-15x=9-3-8x=6We divide both sides with 2 so that we get a smallest possible answer.-4x=3I hate dealing with negative X's. it is so... negative..Multiply both sides with -1 and you get:4x=-3If you need to find X alone, then divide by 4 on both sides.x=-3/4 or in decimal terms it will be:x=-0.75And that is the end of the story :-)
What is the value of x when -119-7x equals 8x plus 16?

What is the answer to the math problem 15x plus 22 equals 7x plus 62?
You have to use Orger of Operations, or BEDMAS (Brackets, Exponents, Division, Mulitplication, Addition, Subtraction).And I'm not doing your Math Homework for you. Sorry.Another contributor's answer:15x+22 = 7x+6215x-7x = 62-22The x's and numbers have been collected together, notice the changes with the + and - signs. This is done to keep the equation in balance.8x = 40Divide both sides of the equation by 8 to find the value of x:x = 5
