Answer:

x = 7

Step-by-step explanation:

Solve equation [2] for the variable  y

[2]    y = - 2

Plug this in for variable  y  in equation [1]

[1]    (-2) - 2x = -16

[1]     - 2x = -14

Solve equation [1] for the variable  x

[1]    2x = 14

[1]    x = 7

Solution:
y = -2
x = 7

ITS URGENT PLEASE HELP Which equation represents the line that is parallel to y=3/7x+11 and passes through (-21,42)?
Pepsi [2]

Answer:

y = 3/7x + 51

Step-by-step explanation:

y = 3/7x + 11 is parallel to the line so it means that both of their gradient are same so:

y = mx + c

m= gradient point = (-21 , 42)

= 3/7

now we sub the m and the point into the formula which is y= mx+c because we should find the c first then we can find the equation of the line:

42 = 3/7 (-21) + c

42 = -9 + c

42 + 9 = c

51 = c

c = 51

now you hv to rewrite again the equation become y= 3/7x + 51

So now your final answer is : y = 3/7x +51
