How do you solve y plus 2 plus 3x equals 7x?

Answer 1

y + 2 + 3x = 7x

Subtract 3x from each side of the equation:

y + 2 = 4x

Subtract 2 from each side:

y = 4x - 2

Inspecting the equation in this form, we see immediately that

it's the equation of a line with slope of 4 and y-intercept of -2 .

-- On a blank graph, mark a point on the y-axis at [ y = -2 ].

-- Mark a point on the x-axis at [ x = 0.5 ].

-- Using a straight edge and pencil, connect the two points,

and extend the line as far in each direction as possible.

-- Every point on the line is a solution of the equation. There are

an infinite number of them.
