Multiply the second equation by 3, so 4x-y=6 becomes 12x-3y=18.
x + 3y = -5
+ (12x-3y = 18)
______________
13x = 13
So x = 1
Plug x = 1 into any of these, such as 1 + 3y = -5, which becomes 3y = -6, and then y = -2.
x = 1
y = -2
Answer:
1,6 and 6,6
Step-by-step explanation:
since they are on the same y-axis, changing the x-value shouldn't matter.
A = 1/2h(b1 + b2)
2A = h(b1 + b2)
2A/h = b1 + b2
b1 = 2A/h - b2
