I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7
II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)
Answer:
Step-by-step explanation:
ok so y= 7-2x just need to move 2x to the other side
Answer:
Step-by-step explanation: •Subtract 2x from both sides of the equation.
-3y = 12 - 2x
•Divide each term by -3y = 12 - 2x by -3.
-3y/-3 = 12/-3 + -2x/-3
•Cancel the common factor of -3.
12/-3 + -2x/-3
•Divide y by 1.
y = 12/-3 + -2x/-3
•Simplify each term.
•Divide 12 by -3.
y = -4 + -2x/-3
•Dividing two negatives values results in a positive value.
y = -4 + 2x/3
