Hel pl Correct the error in solving the equation.

-2(7-y)+4=-4
-14-2y+4=-4
-10-2y=-4
-2y=6
y=-3

Y=3

Step-by-step explanation:

in the first to second step: -2(7-y)+4=-4 to -14-2y+4=-4, the part -2(7-y) should equal -14+2y instead of 14-2y because two negative signs add to be positive

so y should be 3

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
