Answer:
2x +3y=1⇒equation 1
3x=2y+8
3x-2y=8⇒equation 2
by elimination method,
2x+3y=1 ×2
3x-2y=8 ×3
4x+6y=2
9x-6y=24
cut 6y and -6y
4x+6y=2
9x-6y=24
---------------
13x+0=26
13x=26
x=26/13
x=2
substitute x=2 in equation 1
2(2)+3y=1
4+3y=1
3y=1-4
3y=-3
y=-3/3
y=-1
therefore, x=2 and y=-1
hope it helps u!
Answer:

Step-by-step explanation:
Answer:
y = -5x - 19
Step-by-step explanation:
Find the y intercept using slope intercept form [ y = mx + b ]
y = -5x + b
-4 = -5(-3) + b
-4 = 15 + b
-19 = b
y = -5x - 19
Best of Luck!
Answer:
