Answer:
3/4*x - 3/4*8=12
3/4x -6=12
3/4x=12+6
3/4x=18
x=24
Step-by-step explanation:
multiply 3/4 into the content inside the brackets
have -3/4*8 cross the equal sign changing its sign from - to +
divide both sides by 3/4
Answer:
y = -3x + 21
Step-by-step explanation:
(5,6)
y = mx + b
6 = -3 × 5 + b
solving for b
b = 6 - (-3)(5)
b = 21
Therefore,
y = -3x + 21
