Question

Select steps that could be used to solve the equation 1 + 3x = -x + 4.

Answer 1

Combine like terms (I might be slow, i'm working in two qs at once)

Answer 2

which means following the Golden Rule of Algebra: subtract 1 from both sides of the equation:
1-1+3x= -x+4-1
3x=-x+3
Add x to both sides:
3x+x=-x+x+3
4x=3
x=3/4

Answer 3

have a good day
