3x+8 = 12 3x = 4 x = 4/3
true. 5+3=8 8+7=15 5+7=12 12+3=15
40
X=5/12
first add 12 plus 12 equals 24, then add 4 plus 4 and that equals 8. 24 plus 8 equals 32. 12 + 12 = 24 4 +4 =8 24 + 8 =32
5 + -8 = 3 + 12 -3 is not equal to 15
12-5-2+3 = 8
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
3x+8 = 12 3x = 4 x = 4/3

Yes, -8 plus plus 3 equals -5. The "plus plus" is equivalent to a positive sign, so -8 plus (+3) equals -5.
11/12; 1/4=3/12 & 2/3=8/12 so 3/12+8/12=11/12
