Answer:

Step-by-step explanation:

You could look it up just like me! So here's what someone else did on brainly so I don't take credit btw.

One.

To solve this, first combine like terms.

6x + 4x - 6 = 24 + 9x

10x - 6 = 24 + 9x

Then move all like terms to one side.

10x - 9x = 24 + 6

x = 30

How substation y=3x-7 <br> 2y+4x=36

SSSSS [86.1K]

The solution is:

x = 5

y = 8

Step-by-step explanation:

Given equations are:

$y=3x-7\ \ \ Eqn\ 1\\2y+4y = 36\ \ \ Eqn\ 2$

Putting y = 3x-7 in equation 2

$2(3x-7)+4x = 36\\6x-14+4x = 36\\10x-14 = 36\\10x = 36+14\\10x = 50$

Dividing both sides by 10

$\frac{10x}{10} = \frac{50}{10}\\x = 5$

Putting x=5 in eqn 1

$y = 3(5)-7\\= 15-7 = 8$

Hence,

x = 5

y = 8

How do i solve for y?

harkovskaia [24]

Answer:

$y\geq 4+\frac{7x}{4}$

Step-by-step explanation:

$7x-4y\leq -16$

Subtract 7x from both sides to isolate y

$7x-7x-4y\leq -16-7x$

$-4y\leq -16-7x$

Divide both sides by -4 to isolate y

$\frac{-4y}{-4}\leq \frac{-16-7x}{-4}$

Simplify and flip the $\leq$ because you are dividing by a negative number

$y\geq 4+\frac{7x}{4}$

Finito.
