Which of the following is a linear equation?
Sedbober [7]

2x - 3y = 7 can be rewritten as y = 2/3x - 7/3, therefore, the equation that is a linear equation is: C. 2x - 3y = 7.

<h3>What is a Linear Equation?</h3>

A linear equation is expressed in the slope-intercept form as y = mx + b.

2x - 3y = 7, rewritten in slope-intercept form would be:

-3y = -2x + 7

y = -2x/-3 + 7/-3

y = 2/3x - 7/3

m = 2/3 and b = -7/3

Therefore, the equation that is a linear equation is: C. 2x - 3y = 7.

4x-16+14=16-4x+6.
4x-16+14-16+4x-6=0(bring all values at one side)
4x+4x+14-16-16-6=0(arrange)
8x-24=0(solve)
8x=24(bring 8 on right hand side so x is alone)
X=24/8(solve)
