Given a function described as equation y = 3x + 4, what is y when x is 1, 2, and 3?

when x=1,  y=7. when x=2, y=10. when  x=3, y=13

Step-by-step explanation:

x=1 into y=3(1)+4

y=3+4

y=7

x=2 into y=3(2)+4

y=6+4

y=10

x=3 into y=3(3)+4

y=9+4

y=13

Hope this helps all you do is insert the x value in for x and solve for y!! Please mark Brainliest.

1. x = 1, y = 7

2. x = 2, y = 10

3. x = 3, y = 13

Step-by-step explanation:

1. When x is 1 in y = 3x + 4

Replace the x in 3 to 1.

Then it becomes 3(1) + 4

3 x 1= 3

3 + 4= 7

2.  When x is 2 in y = 3x + 4

Replace the x in 3 to 2.

Then it becomes 3(2) + 4

3 x 2= 6

6 + 4= 10

3. When x is 3 in y = 3x + 4

Replace the x in 3 to 3.

Then it becomes 3(3) + 4

3 x 3= 9

9 + 4= 13

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
