Hey there!
3x + 28 = 46
SUBTRACT 28 to BOTH SIDES
3x + 28 - 28 = 46 - 28
CANCEL out d 28 - 28 because it give you 0
KEEPs 46 - 28 because it help solve for the x-value.
NEW EQUATION: 3x = 46 - 28
SIMPLIFY IT!
3x = 18
DIVIDE 3 to BOTH SIDES
3x/3 = 18/3
CANCEL out: 3/3 because it give you 1
KEEP: 18/3 because it give you the x-value.
NEW EQUATION: x = 18/3
SIMPLIFY IT!
x = 6
Now that we have your x-value we can substitute it into the equation of: 2x + 6
SIMPLIFYING:
2x + 6
= 2(6) + 6
= 12 + 6
= 18
Thus, your answer is: 18
Good luck on your assignment & enjoy your day!
