Try another version of this question Box 1: Enter your answer as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4) Step 1: We must first combine like terms on the left hand side
Solve the equation for the given variable. If no solution, write "NA". If thre are infinite solutions, type "oo"
`4 x + 3 - 8 x + 9 = -4 x + 12`
Answer: `x` =
Enter DNE for Does Not Exist, oo for Infinity `oo`
4 x - 8 x + 3 + 9 = -4 x + 12
-4 x + 12 = -4 x + 12
Step 2: Next, move the variables to one side, and the constants to the other side
-4 x - -4 x = 12 - 12
0 = 0
Since the variables cancel, and we are left with 0 = 0, the answer is infinite solutions (all real numbers)
