Find the solution of system of equation
y = 2x - 1
y= 3x + 2

x = -3    and y = -7

The solution to the system of equation is (-3, -7)

Step-by-step explanation:

y = 2x - 1

y = 3x + 2

We can solve this system of equation by either elimination method or substitution method or both.

We will use substitution method to solve this.

y = 2x - 1 (1)

y = 3x + 2(2)

Substitute equation(2) into equation (1)

3x + 2  =  2x - 1

subtract 2x from both-side of the equation

3x -2x + 2 = 2x - 2x - 1

x + 2=-1

subtract 2 from both-side of the equation

x + 2 - 2 = -1 -2

x = -3

Substitute x = -3 in equation (1)

y = 2x - 1

y = 2(-3) - 1

   =-6 -1

    = -7

y=-7

x = -3    and y = -7

Therefore the solution to the system of equation is (-3, -7)
