how do you solve 4x-3+2x+21

Question

i need to find x for this equation

4x-3+2x+21=60

Answer 1

Hello, this actually is not solvable because what you have written is defined as a mathematical expression. Only equations (math sentences with an "=") are solvable. But if we can assume that you meant to write

4x-3+2x+21 = 0

then what you have to do is combine like terms. First combine all the "x" terms. In your problem, you have 4x and 2x which can be combined to equal 6x. Next you have (-3) and 21 which can be combined to equal 18. The equation simplifies to 6x+18 = 0. Next, subtract 18 from both sides of the equation to make the equation read

6x = (-18)

Now you can divide 6 from both sides and you get

x = (-3)

Hope this helps!
