Change to proper fraction
Steps(Another Way):
Change the fraction to improper fractions.
Reduce by crossing it(5 and 15 reduced to 1 and 3; 4 and 14 reduced to 2 and 7.)
Change answer to proper fraction.
Answer:
<u>y = mx + b</u>
m = slope = -2
To find the y-intercept(b), substitute the points into the function:
-3 = -2(-5) + b
-3 = 10 + b
b = -3 - 10 = -13
Therefore, y = -2x - 13
Answer:
1. 4x+3x were added together because they are like terms
2. We subtracted 5 from both sides of the equation
3. We divide both sides of the equation by seven

Answer: x = 37 and y = 11
Explanation:
Let x be the bigger number
Let y be the smaller number
x + y = 48
But x is 7 less 4 times the smaller number.
=> x = 4y - 7
Substitute this value of x:
4y - 7 + y = 48
5y = 48 + 7
5y = 55
y = 11
Substitute the value of y in to the equation:
x + 11 = 48
x = 48 - 11
x = 37
Therefore, x = 37 and y = 11
