3.4w=−5.1

w=1.5

w=1.7

w=−1.5

w=−1.7

w = -1.5

Step-by-step explanation:

To solve for w in the question below;

3.4 w=−5.1

All we need to do is to divide both-side of the equation by 3.4

3.4 w/3.4 = −5.1/3.4

On the left-hand side of the equation, 3.4 at the numerator will cancel-out 3.4 at the denominator leaving us with just w, while on the right-hand side of the equation negative 5.1 will be divided by 3.4. That is

w = -5.1/3.4

w = -1.5

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
