Help this type of work confuses me
Dmitrij [34]

Answer/Step-by-step explanation:

Given:

-x + 3x + 1 + 4(x + 2) = 54

To solve, first open the bracket by applying the distributive property. Multiply every term you have in the bracket by 4

-x + 3x + 1 + 4x + 8 = 54

Add like terms together

6x + 9 = 54

Subtract 9 from each side

6x = 54 - 9

6x = 45

Divide both sides by 6

x = 45/6

x = 7.5

What does the line 6x+2y=8 look like
sdas [7]
To determine what the line looks like, simply change it to y = mx + b form. Then simply either make a table of values. And substitute any points into the equation and obtain points to plot on the graph. Or you can simply plot the graph by using the slope of the equation.

Y = 8 - 6x/2
Y = 4 - 3x
Y = -3x + 4.

This would be the rearranged equation.
