Answer:

60,120

Step-by-step explanation:

a = 4x + 12 \\ b = 2(4x + 12) \\( 4x + 12) + 2(4x + 12) = 180 \\ 4x + 12 = 180 \div 3 \\ 4x = 48 \\ x = 12 \\  \\ a = 60 \\ b = 120

Is x = 6 a solution to the equation 5(x – 3) = x + 13?
deff fn [24]

Answer:

x=6 is not a solution

Step-by-step explanation:

We can substitute 6 as x to find out:

5(6-3)=6+13

first, because of PEMDAS we'll do 6-3

5(3)=6+13

multiply 5 by 3 and add 6 and 13

15=19

Since the statement is not true, that means that x=6 is not a solution

Hope this helps!

kakasveta [241]

Answer:

x =  -12

y = 3

Step-by-step explanation:

1/2x + 6(x+15) = 12\\1/2x + 6x + 90 = 12\\6\frac{1}{2} x + 90 = 12\\6\frac{1}{2} x= -78\\x = -12

y = x + 15\\y = -12 + 15\\y = 3
