3x-2 (x + 3) / 3 = 16 - (x + 2) / 2 - (X-2) / 6, please
Multiply 6 on both sides to get 18x-4x-12 = 96-3x-6-x + 2, and merge the similar terms to get 18x = 108 x = 6
If 3x + 1 = 6, then 3x-2.5=
A.2.5 B.3 C.2
3x + 1 = 6 leads to 3x = 5
therefore
3x-2.5=502.5=2.5
Choose a
3x-6 x-3 = 9 x + 5
3x-6 x-3 = 9 x + 5
54x-3(x-3)=2(x+5)
54x-3x+9=2x+10
51x-2x=10-9
49x=1
x=1/49
Solve the system of inequalities: 12x − 1 ≤ 04 − 3x < 14 − x, and express its solution set on the number axis
From 12x − 1 ≤ 04 − 3x ＜ 14 − x, the solution set of X ≤ 2x ＞ − 5 (4 points) inequality system is - 5 ＜ x ≤ 2. (5 points) solution set is expressed on the number axis as: (6 points)
