Answer:
68
Step-by-step explanation:
Step 1: Convert fraction to improper
4 1/4 = 16/4 + 1/4 = 17/4
Step 2: Multiply 16 and 17/4
16(17/4) = 272/4 = 68
-4 = y + 3
y = -4x - 3
Solve for Y in the first equation:
-4 = y +3
Subtract 3 from both sides:
y = -7
Now using the addition method:
rewrite the second equation as 4x+y = -3
Multiply y = -7 by - 1 to get -y = 7
Now add the two together:
4x +y = -3
-y =7
4x = 4
Divide each side by 4:
x = 4/4 = 1
Then replace x in one of the equations to solve for y which is -7
X = 1, Y = -7
