Answer:
4x+2x=90
6x=90
x=15
Step-by-step explanation:
Y-5=3-9(y+2). so so u are going to distribute-9 to y and 2 which is -9y-18
so u are going to add like terms 3 and -18 which is -15. so the next step is going to be y-5=-9y-15 so u are going to add 5 to -5 and -15 to balance the equation and u will get -10 . y=-9y -10. since u are multiplying -9 by y so have to expand it y= -9 * y -10. so u have to divide y by y to get y . -9-10= -19 soo y =-19
Answer:
/2 and /4 because angle 1 is 90
