For which equation is x = 1 a solution? please show work A 4 - x = 1
B 4x = 1
C x +3= 4
D x/4 = 1
please answer as soon as possible

B

Step-by-step explanation:

Thats my own understanding

C x +3= 4           becomes 1 + 3 = 4  TRUE

Step-by-step explanation:

In each case, substitute 1 for x and then determine whether or not the resulting equation is true.

A 4 - x = 1         becomes 4 - 1 = 1  FALSE

B 4x = 1             becomes 4(1) = 1   FALSE

C x +3= 4           becomes 1 + 3 = 4  TRUE

D x/4 = 1            becomees 1/4 = 1    FALSE

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
