Try out all of your options by filling the the x and y values from each option. You can use either of the two equations to solve

1) 2(2)+3(3) does not equal 5
2) 2(3)+3(2) does not equal 5
3) 2(3)+3(-2) does not equal 5
4) 2(-2)+3(3) equals 5
4.5) Double check your answer by doing the same thing for the second equation // 3(-2)+2(3) does equal zero.

HELP QUESTION NUMBER FOUR
enyata [817]

Answer:

x = -1 and y = -1.

Step-by-step explanation:

The given system of equations are :

y = 4x + 3 ....(1)

y = -x - 2 ....(2)

From equation (1) and (2) :

4x + 3 = -x - 2

Taking like terms together,

4x + x = -3 -2

5x = -5

x = -1

Put the value of x in equation (1)

y = 4(-1) + 3

= -1

The solution is also shown in the attached figure. Hence, the solution is x = -1 and y = -1.
