solve : (1) 7x+4x/x+2=4/3 (2) 2x=7/5
Answers
Answer:
1)
7x+4x/x+2=4/3
3(7x+4x)=4(x+2)
21x+12x=4x+8
33x-4x-8=0
29x-8=0
29x=8
x=8/29
2)
2x=7/5
5×2x=7
10x=7
x=7/10

Answer:
(1) x = -2/3
(2) x = 7/10
Step-by-step explanation:
(1) 7x+4x/x+2=4/3
1 . Cancel terms that are in both the numerator and denominator.
= 7x + 4x / x +2 = 4/3
= 7x + 4/1 + 2 = 4/3
2 . Add the numbers
= 7x + 4+2 = 4/3
= 7x + 6 = 4/3
3. Subtract 6 from both sides of the equation
= 7x + 6 = 4/3
= 7x + 6-6 = 4/3 - 6
4. Simplify
|
• Subtract the numbers
|
• Subtract the numbers again
\/
7x = -14/3
5. Divide both sides of the equation by the same term
= 7x = -14/3
= 7x/7 = -14/3 / 7
6. Simplify
|
• Cancel terms that are in both the numerator
and Denominator
|
• Divide the Numbers
\/
x = - 2/3
7. Solution
x = -2/3
(2) 2x = 7/5
1 . Divide both sides of the equation by the same term
= 2x = 7/5
= 2x / 2 = 7/5 / 2
2. Simplify
|
• Cancel terms that are in both the numerator and Denominator
|
• Divide the Numbers
\/
x = 7/10
3. Solution
x = 7/10
