Answer:
y=-14x+170
Step-by-step explanation:
y=mx+b
2=-14(12)+b
2=-168+b
170=b
y=-14x+170
Answer:
(3, 4 )
Step-by-step explanation:
3x - y = 5 → (1)
x + y = 7 → (2)
adding the 2 equations term by term will eliminate y
4x + 0 = 12
4x = 12 ( divide both sides by 4 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (2)
3 + y = 7 ( subtract 3 from both sides )
y = 4
solution is (3, 4 )
Step-by-step explanation:
is it like this ? no diagrams ?
