Answer:
16
Step-by-step explanation:
5y=6x+16...(I) and 9x=7y-20....(ii)
Using substitution method:
Multiply equation ii by 5
45x=35y-100
Substitute (I) into ii
45x=7 * 5y - 20
45x=7(6x+16)
45x=42x+112
45x-42x=112
3x=112......…….......
5y=6x+16
5y=2*3x+16
5y=2*112+16
5y=224+16
5y=240
Divide both sides by 5
y=48
3x-2y
112-2*48
112-96
16

Answer:
y = 3
Step-by-step explanation:
PQ(5 - 12;-10 + 2) => PQ(-7;-8)
RS(8; y - 10)
because PQ⊥RS
=> (-7).8 - 8(y - 10) = 0
<=> y - 10 = -7
<=> y = 3
