Answer:
X = 3/5
Step-by-step explanation:
2/x=4/5x+2
Find the LCM of the denominator 5x and 1
2/x =4/5x + 2/1
2/x = (4 + 10x)/5x
Cross multiply the equation
2× 5x = (4+ 10x) × x
10x = 4x + 10x^2
Collect like term of the mixed number
10x - 4x = 10x^2
6x = 10x^2
Divide both side by 2x
6x/2x = {10x^2 } / 2x
3 = 5x
Divide both side by the coefficient of x
3/5 = 5x/5
X = 3/5
Answer:c
Step-by-step explanation:
Answer:
Step-by-step explanation:
Your first equation is y=10x+20
Your slope is 10 and your y-intercept is 20 in this first equation
Your second equation after it has changed, your new equation is y=30x+45
Your slope is 30 and your y-intercept is 45 in this second equation
I hope this helps!
