54 / 4 simple math honey, let me know if you need more help my door is always open!
Point-slope equations take the form y-y1 = m(x - x1)
y1 = -2, x1 = 1, m = 3
y + 2 = 3(x-1)
Answer:
x = 8, y = 4
Step-by-step explanation:
x = 3y-4
2x - 8 = 2y
x - 4 = y
x = y + 4
substitute top equation to this equation
3y-4 = y+4
2y = 8
y = 4
now substitute this into second equation
x = y + 4
x = 8
check answer with first equation
x = 3y-4
8 = 3(4) - 4
8 = 8; correct
