Answer:
a = 6
b = 3/4
Step-by-step explanation:
They both need to have the same slope.
The slope in the first equation is 6
That means that the second equation must have a = 6
They both need to have the same y intercept
The second equation has a y intercept of 3/4
Therefore b in the first equation, must be 3/4
Answer:

Step-by-step explanation:
So we have the equation:

First, distribute the left side:

Add values on the left side:

Add 7 to both sides. The right side cancels:

Subtract 2x from both sides. The left side cancels:

Divide both sides by -6:

Therefore, x equals -3.
3x^2 = 2(x + 4)
3x^2 = 2x + 8
3x^2 - 2x - 8 = 0
(3x + 4)(x - 2) = 0
3x + 4 = 0
3x = -4
x = -4/3
x - 2 = 0
x = 2
solution is : x = -4/3 or x = 2 <==
