Answer:
x = 5/3
Step-by-step explanation:
Solve for x:
7 x - 15 = -2 x
Add 2 x to both sides:
7 x + 2 x - 15 = 2 x - 2 x
2 x - 2 x = 0:
7 x + 2 x - 15 = 0
7 x + 2 x = 9 x:
9 x - 15 = 0
Add 15 to both sides:
9 x + (15 - 15) = 15
15 - 15 = 0:
9 x = 15
Divide both sides of 9 x = 15 by 9:
(9 x)/9 = 15/9
9/9 = 1:
x = 15/9
The gcd of 15 and 9 is 3, so 15/9 = (3×5)/(3×3) = 3/3×5/3 = 5/3:
Answer: x = 5/3
Answer:
Given the equation, −6y + 7= 24x + 25, you'll have to transform this equation into its slope-intercept form, y = mx + b:
−6y + 7 = 24x + 25
Subtract 7 from both sides:
−6y + 7 − 7 = 24x + 25 − 7
−6y = 24x + 18
Divide both sides by −6:
y = -4x - 3 ← This is the <u>slope-intercept form</u>, where m = slope and b = y-intercept.
Next, you need to find at least two points to plot on your graph. We can do this by using the y-intercept, (0, -3). Using the slope, -4 and the y-intercept (0, -3):
Start at (0, -3) then go 4 units down (because it is a negative slope) and 1 unit to the right. Your next point should be (1, -7). You can connect those two points and create a line.
The attached screenshot shows the graph of the linear equation, y = -4x - 3.
