Question

Which method will you use to simplify the expression "3x + 5 x + 4 " ?​

Answer 1

Combining like numbers

Explanation:

Like nunbers are numbers that share the same exponent and variable. All the variables in this equation are 1, so we can ignore that. 3x and 5x share a variable, but 4 does not, so we can combine 3x and 5x to get 8x+4
