Answer:

X=6. Y= - 6

Step-by-step explanation:

Put y=6-2x in b)

4x+3(6-2x)=6

4x+18-6x=6

-2x=6-18

- 2x=-12

Divide both sides by - 2

X=6

Put x=6 in y = 6-2x

Y=6-2(6)

Y=-6

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. y−3x=18
Radda [10]

Answer:

see explanation

Step-by-step explanation:

Given

y - 3x = 18

To find the y- intercept let x = 0 in the equation and solve for y

y - 3(0) = 18

y - 0 = 18

y = 18 ⇒ (0,18 ) ← y - intercept

To find the x- intercept let y = 0 in the equation and solve for x

0 - 3x = 18

- 3x = 18  ( divide both sides by - 3 )

x = - 6 ⇒ (- 6, 0 ) ← x- intercept

Consider the equations 5x+10=30 and 5(x+10)=30. Do they have the same solution? Why or why not?
hodyreva [135]
If you simplify (take out the brackets) of this equation. 5(x+10)=30 then it would be

5 times x + 5 times 10 = 30

5x+10=30

So yes they have the same solution
