2/3 x − 9 − 2x + 2 = 1
which is an equivalent equation after combining like terms?
a 8 / 3 x-11 = 1
b -4 /3x -7 =1
c 8 / 3 x - 7=1
d -4 / 3 x -11=1

it is x equals 3   plese mark me really need it

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
