Solve the system of equations using the substitution method.

y=2x-1

y=3x+3

Choose the ordered pair that solves both equations.

(4,7)

(2,5)

(-4, -9)

(-1,3)

(-4,-9)

Step-by-step explanation:

both equations are equal to y, y=2x-1 and y=3x+3, which makes them equal to eachother, 2x-1=3x+3

2x-1=3x+3, make x the subject:

subtract 2 (-2) from both sides

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

-1=x+3

subtract 3 (-3) from both sides

-3-1=x+3-3

-4=x

therefore, x=-4

substitute x into any 1 of the original equation to get y:

y=2x-1

y=2(-4)-1

y=-8-1

y=-9

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
