Using the substitution method what is the poi of y=4x-5 and y=2/3x+5

(x,y) = (3,7)

Since both equations express y in terms of x we can equate them.

4x - 5 =2/3x + 5 (subtract 2/3x from both sides )

10/3x - 5 = 5 (add 5 to both sides)

10/3x = 10

multiply both sides by 3/10

x = (3× 10)/10 = 3

substitute x = 3 in either of the 2 given equations to obtain y-coordinate

y = 4x - 5 ⇒ y=(4 × 3) - 5 = 12 - 5 = 7

point of intersection = (3,7)

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
