2(21x − 7) + 4(3x + 2) = 6(2x + 9) + 3
42x - 14 + 12x + 8= 12x + 54 + 3
54x - 6= 12x + 57
54x=12x + 63
42x=63
x= 63/42
x= 3/2
Answer:
an apparent solution that must be rejected because it does not satisfy the original equation.
Step-by-step explanation:
222222222222-22111111111111111
= - 2.2111 × 10^16
Answer:
no solution
Step-by-step explanation:
6y≥42
Divide each side by 6
6y/6≥42/6
y≥7
Then solve the second one
4y+12≤0
Subtract 12 from each side
4y+12-12≤0-12
4y ≤-12
Divide each side by 4
4y/4 ≤-12/4
y ≤-3
There is no solution since there is no overlap
Answer:
x-8 to get the zero for the 8 you have to add it. And for the second part you have to subtract four from itself.
