Answer:
$16
Step-by-step explanation:
1/4x4=1
So 4x4 = 16
To find an inverse, switch the x and the y and solve for the new y. Yours switched is x = 3y. Now solving for y we divide both sides by 3 to get y = x/3
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
Answer:
9 × 7 + (8 - 5) = 66
Step-by-step explanation:
9 × 7 + 8 - 5 = 66
Applying the order of operations (PEMDAS);
The parenthesis would go to 9 × 7 + (8 - 5) = 66
