You can use substitution or elimination method to solve. <em>I used substitution.</em>
2(1/2y + 5) + 3y = -14
y + 10 + 3y = -14
4y + 10 = -14
4y = -24
y = -6
x = 1/2y + 5 = 1/2(-6) + 5 = -3 + 5 = 2
x = 2, y = -6

Answer:
y = 4x - 28
Step-by-step explanation:
When two lines are parallel, their slope stays the same. thus we have y = 4x (so far)
Then use the point (8, 4) to plug in the coordinates to y = 4x + b
y = 4x + b (because y-intercept changes)
4 = 4(8) + b
4 = 32 + b
b = 4 - 32
b = -28
the y-intercept is -28 and the equation of the line that passes through the point (8, 4) and is parallel to the line y = 4x + 2 is y = 4x - 28
