If 4(x – 3) + x = –2x + 10, what is the value of x? ​

x=22/7

Step-by-step explanation:

4x-12+x=-2x+10

5x-12=-2x+10

5x=-2x+10+12

5x=-2x+22

5x+2x=22

7x=22

x=22/7

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
