How do u solve <br> 131 + 16x = -331 + 5x
Veronika [31]
The goal of this equation is to solve for x. So, we can start by combining like terms.
(16x) and (5x) are like terms, so we would subtract (5x) over to the other side.

131 + 16x -5x = -331 + 5x - 5x
131 + 11x = -331

Then, we can combine the other like terms, which would be (131) and (-331). Subtract 131 on both sides.

131 - 131 + 11x = -331 - 131
11x = -462

Now, we need to divide the number before x, or the coefficient.

11x/11 = -462/11
x = -42

Determine the intercepts of the line. y=4x+7
luda_lava [24]
To get your answer we'll plug 0 in for x into the equation.

So, multiply 4*0 which equals 0.

y=0+7

Then we'll add 0 and 7 which leaves us with 

y=7

The y-intercept of this equation is: (0,7)

To find the x-intercept of this equation we'll rewrite it as 4x+7=0

Then we'll subtract 7 from both sides,

4x=-7

Now we'll divide each side by 4. Then simplify which brings us to our answer,

x= -\frac{7}{4}

The x-intercept of this equation is: ( -\frac{7}{4} ,0)

I hope I helped you! If you need any more help let me know!
