Answer:
A and B.
Step-by-step explanation:
A.) 2x+6=2:
Move all terms that don't contain x to the right side and solve.
x=−2
B.) 2(x-4)=6x:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−2
C.) 3x+1/2=1/4x+6:
Solve for x by cross multiplying.
x=2
D. 3x+15=2x+9:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−6
