1+1=2 good luck so have a good day
Subtract 15 from both sides that gets rid of 15 and your left with 3b =30b divide 3 on both sides and the answer is 10
(4*2)-(2*-3)+(5*5)= 8-6+25= 27
Answer:
x + 2(2x-4) = 10
Step-by-step explanation:
Here in this question, we want to select which is the correct answer if we substitute for the value of y in the second equation, using the first.
In the first, we have;
y = 2x -4
Now, let’s input this value of y into the second equation.
By direct substitution, what we have is the following;
x + 2y = 10
—-> x + 2(2x -4) = 10
