Answer:
A. 15
B. 16
C. 21
Step-by-step explanation:
A. ((3x5)/2)x2 = 15
B. ((4x2)/2)x4 = 16
C. 5x5 - 2x2 = 21
X = 18
2x - 26 = 10
+26 +26
————————
2x = 36
—- ——
2 2
x = 18
So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

Next, now that we have the value of y, substitute it into either equation to solve for x:

<u>And this is how you get your final answer (5,2).</u>
Answer:
C
Step-by-step explanation:
b is the y value of the equation.
8a = -3b - 5 Let b = - 7
8a = -3*-7 - 5 Combine
8a = 21 - 5 Combine the right again.
8a = 16 Divide by 8
8a/8 = 16/8
a = 2
