Answer: 5x = 12 + 3
5x = 15 (divide both sides by 5 to get x)
Step-by-step explanation:

Answer: 3082.2
Step-by-step explanation:
You’re given that m=7 (slope is 7), so setup the slope-intercept form with that info: y = 7x + b.
Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.
11 = 7*3 + b
Notice the only variable left is b, so you’ll find b this way.
11 = 21 + b and then subtract 21 from both sides:
11 - 21 = b
-10 = b
Plug that back into the equation and you have y = 7x -10
Answer:
x+4+2x = 20+5x-32
Step-by-step explanation:
x+4+2x
= 3x + 4
20+5x-32
= 20-32+5x
= 5x-12
Finding the value of X
3x+4 = 5x-12
= 4+12 = 5x-3x
= 16 = 2x
= 16/2 = X
= 8 = X
By putting the value of X in the equation
(3×8)+4
= 24 +4
= 28
(5×8)-12
= 40-12
28
28 = 28
so the X+4+2x < 20+5x-32 is wrong
