Answer:
x=2 and y=6; (2,6) are coordinate points
Step-by-step explanation:
5x-y=4........i)
2x+2y=16.....ii)
multiply eq.i) by 2
10x-2y=8...iii)
add eq ii and iii
10x-2y+2x+2y=8+16
12x=24
x=2
put x=2 in eq i
5(2)-y=4
10-4=y
6=y
Pretty sure it would be 21x^2+16x+17y
Answer:
n = -101/90
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(1+9n) (10) = −91
(1) (10) + (9n) (10) = −91 (Distribute)
10 + 90n = −91
90n + 10 = −91
Step 2: Subtract 10 from both sides.
90n + 10 − 10 = −91 − 10
90n = −101
Step 3: Divide both sides by 90.
90n/90 = −101/90
n = −101/90
