5x+4-2x là biểu thức đại số
Answer:
7/11
Step-by-step explanation:
7y +6+4y+13=26
firstly collect like terms
7y+4y+6+13=26
11y+19=26
11y=26-19
11y=7
then divide through by 11
y=7/11
you use cubic measurements
hopes this helps
c possibly
CU=-3(5,-12)
CU=36-15
CU=21
The answer is A=21
•you divide both sides by 21 to leave x alone
