Mary: x yrs old
Mike: 3x yrs old
In four yrs:
Mary: x+4 yrs old
Mike: 3x+4 yrs old
As the text of task:
3x+4=2(x+4)
3x+4=2x+8
3x-2x=8-4
x=4
Mary is 4 yrs old
Hey there!
“12x - 24 = 180”
ADD by 24 on BOTH SIDES
12 - 24 + 24 = 180 + 24
CANCEL out: -24 + 24 because that gives 0
KEEP: 180 + 24 = 204
New equation:
12x = 204
DIVIDE 12 on BOTH SIDES
12x / 12 = 204 / 12
CANCEL out: 12 / 12 because of that gives you 1
KEEP: 204 / 12 because that gives the value “x”
204 / 12 = x
204 / 12 = 17
x = 17 ☑️
Good luck on your assignment and enjoy your day!
