7 + x - (3 + 32 = 8) = 3

X=3

Step-by-step explanation:We simplify the equation to the form, which is simple to understand  

7+x-(3+32/8)=3

Simplifying:

7+x-(3+4)=3

Simplifying terms in parentheses

7+x-(+7)=3

Remove unnecessary parentheses

7+x-7=3

We move all terms containing x to the left and all other terms to the right.  

+1x=+3-7+7

We simplify left and right side of the equation.  

+1x=+3

We divide both sides of the equation by 1 to get x.  

x=3

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
