Answer:
16x -12y = 4
15x +12y = 27
Step-by-step explanation:
4x-3y = 1
5x+4y=9
Multiply the first equation by 4
16x -12y = 4
Multiply the second equation by 3
15x +12y = 27
Answer:
p=-9
Step-by-step explanation:
132=-6+3 (1-5p)
-6+3 (1-5p)=132
-6+3 (1-5p)+6=132+6
3(1-5p)=138
3(1-5p)/3=138/3
1-5p=46
1-5p-1=46-1
-5p=45
p=-9
