Hey there!
5x + x - 3 = 3
5x + 1x - 3 = 3
6x - 3 = 3
ADD 3 to BOTH SIDES
6x - 3 + 3 = 3 + 3
CANCEL out: -3 + 3 because it gives you 0
KEEP: 3 + 3 because it helps solve for the x-value
NEW EQUATION: 6x = 3 + 3
SIMPLIFY IT!
6x = 6
DIVIDE 6 to BOTH SIDES
6x/6 = 6/6
CANCEL out: 6/6 (on the LEFT) because it gives you 1
KEEP: 6/6 (on the RIGHT) because it help solve for the x-value (it actually gives it you)
NEW EQUATION: x = 6/6
SIMPLIFY IT!
x = 1
Good luck on your assignment and enjoy your day!
