Verified answer

x = 1

y = 1

(3x+y, x – 1) = (x+3, 2y – 2x)

3x + y = x + 3

x - 1 = 2y - 2x

2x + y = 3

3x - 2y = 1

y = 3 - 2x

3x - 2(3 - 2x) = 1

y = 3 - 2x

3x - 6 + 4x = 1

y = 3 - 2x

7x = 7

x = 1

y = 1

If an equation is contained interior the variety y = mx + b then m is the slope a million. m = -5/2 2. m = -4/3 3. m = -a million 4. m = -4 5. This one isn't contained interior the stunning type so we would desire to located it into slope intercept type 2x - y = a million subtract 2x from the two aspects -y = -2x + a million divide with the help of -a million y = 2x - a million so m = 2 6. x + 2y = -8 subtract x from the two aspects 2y = -x - 8 divide with the help of two y = -(a million/2)x - 4 so m = -a million/2 7. 8x + 3y = -9 subtract 8x from the two aspects 3y = -8x - 9 divide with the help of three y = -(8/3)x - 3 so m = -8/3

3x+y = x+3

x-1= 2y -2x

y = -2x+3

x-1 = 2(-2x+3)-2x = -4x+6-2x = 6-6x

7x=7

x=1

y = -2 +3 = 1

(1,1) - answer

3x+y=x+3

x-1=2y-2x

3x+y=x+3 And x-1=2y-2x

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

y=3-2x...® y=3x-1 over 2. ....©

substitute ® into ©

and you'll get x=1

when x=1, substitute it into any equ and you'll get y=1

hence (x,y)= (1,1)

only one ordered pair which is (x,y)={1,1}.equate 3x+y=x+3 and x-1=2y-2x.solve them.and get the answer

they are both 1
