Answer:
x = -4.8
Step-by-step explanation:
combine like terms
3x + 2x + 6 = -18
5x + 6 = -18
isolate the terms with the x variable
5x + 6 - 6 = -18 - 6
5x = -24
isolate x
5x/5 = -24/5
x = -4.8
Answer:
y = -5x + 20
Step-by-step explanation:
Lets start with the first given values for x and y
(2,10)
Lets try out the first equation
y = 5x + 4
y = 5(2) + 4
y = 14
This equation wouldn't work because the y value is not 10 when the x value is 2
y = 5x + 20
y = 5(2) + 20
y = 30
This equation doesn't work either
y = -5x + 20
y = -5(2) + 20
y = -10 + 20
y = 10
This would be the correct equation since your y value is 10 when the x value is 2
84 ÷ 2 = 42
Check it to make sure.
2 × 42 = 84
42 and 2 can be multiplied to get 84.
