Astudent is solving the equation 2x - 1 = 16x + 2
step 1: 2x - 1 = 16x + 2
step 2: 2x - 1 = (24)x + 2
step 3: 2x - 1 = 24x + 8
which is the next step?
a. 2(x - 1) = 4(x + 2)
b. x - 1 = 4x + 8
c. x - 1 = x + 2
d. x -1 = -(4x + 8)

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
