Hope this helps! :D
Queremos tener todos los variables del mismo typo en un lado así que vamos a mover la -x a la izquierda, y el 15 a la derecha.
15 + 3x = 21 - x
+x +x
————————
15 + 4x = 21
-15 -15
———————
4x = 6
— —
4 4
X = 1.5 para ver si es correcto puedes tratar de poner 1.5 en lugar de la x y te saldrá una ecuación correcta :), déjame saber si tienes preguntas espero que eso hizo sentido.
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have the equations in the standard form. Convert to the slope-intercept form:
<em>subtract 3x from both sides</em>

<em>add x to both sides</em>
<em>divide both sides by 3</em>

We need only two points to plot a graph of each function.

for x = 0 and for x = -3:


for x = 0 and for x = -3:

Look at the picture.
