Answer:

x is equal to -2

the equation is x + 3y = 4

so we substitute the value of 'x' which is -2 in equation x + 3 = 4

Step-by-step explanation:

then we move 3y on left side.

then we add 4 + 2 which is 6.

then it will be, y = 6/3

which is 2

therefore we get y = 2

hope this helps you ☺️☺️

Answer:

Step-by-step explanation:

Since x=-2

-2+3y=4

Add 2 on both sides

3y=6

Divide 3 on both sides

y=2

A line has a slope of 5 and passes through the point (-1,2).

Andreyy89

Answer:

Step-by-step explanation:

slope=m= 5

points=(-1,2)

By point-slope form:

$y$ - $y_{1}$ =m( $x-x_{1}$ )

Substitute the values in formula:

y-2=5(x+1) (It is the point slope form)

Now,

Slope intercept form:

y-2=5x+5

y=5x+5+2

y=5x+7

Solve for q. 3(q − 7) = 27 q =

Whitepunk [10]

Answer:

The answer is, q = 16.

Step-by-step explanation:

1) Divide both sides by 3.

$q - 7 = \frac{27}{3}$

2) Simplify 27/3 to 9.

$q - 7 = 9$

3) Add 7 to both sides.

$q = 9 + 7$

4) Simplify 9 + 7 to 16.

$q = 16$

Therefor, the answer is q = 16.
