The value of y when solving the equation 2(y−6)+3=4y−7 is:

i think its y=-1

Step-by-step explanation:

-1

Step-by-step explanation:

2(y−6)+3=4y−7

2y−12+3=4y−7

2y-12+12+3=4y-7+12

2y+3=4y+5

2y+3-3=4y+5-3

2y-4y=4y-4y+2

-2y=2

-2y/-2=2/-2

y=-1

$9.41

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
