Answer:
Step-by-step explanation:
If the value of y is same for both then we have equal right sides of equations
Solve this for x
- 50x - 30x = 70 - 10
- 20x = 60
- x = 60/20
- x = 3
Find the value of y
- y = 50*3 + 10 = 150 + 10 = 160
Correct choice is A
Answers: (x, y, z) = (1, 2, -1)
Solving Steps:
(a-4)(a+3)/a^2-a / 2(a-4)/(a+3)(a-1)
(a-4)(a+3)/a / 2a-8/(a+3)(a-1)
(a-4)(a+3)/a x (a+3)(a-1)/2a-8
2a-8(a-4)(a+3)
2a^2+32+2a^2-24
2a^2+8
a(a+3)(a-1)
a^2+3+a^2-1
a^4+2
2a^4+8+a^4+2
2a^8+10
Your answer is: 2a^8+10
Have an amazing day and stay hopeful!
