4 plus 3x-1 over 2 =9. find the value of x

4+3x−1ov(2.718282)r(2)=9

Step 1: Add -3x to both sides.

−5.436564orv+3x+4+−3x=9+−3x

−5.436564orv+4=−3x+9

Step 2: Add -4 to both sides.

−5.436564orv+4+−4=−3x+9+−4

−5.436564orv=−3x+5

Step 3: Divide both sides by -5.436564rv.

−5.436564orv

−5.436564rv

=

−3x+5

−5.436564rv

o=

3x−5

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
