Answer: -3.5

Step-by-step explanation:

you plug in -20 into why then you’d have -20=4x-6

the. you add 6 to the -20 to have the x alone.

then you’d have -14=4x

then you divide each side by 4 so -14/4 is -3.5

Answer: - 3.5

Step-by-step explanation:

y = 4x - 6. Given

to calculate for x, for y = - 20

from the given equation,

y = 4x - 6

substitute y = - 20

-20 = 4x - 6

taking like terms

-20 + 6 = 4x

-14 = 4x

divide both sides by 4

-14/4 = 4x/4

x = - 3.5
