Match the property of equality with the corresponding definition given that a = b. subtraction property of equality alc = b/c addition property of equality - a(c) = b(c) multiplication property of equality a + c = b + c division property of equality a-(=b-c

i think asking google will you get the answer to that question

x = 3 ± √(5+y)

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

cause it equals more
