A) x * 7 = y
B) y + 7 +1 = 9x
A) x = y / 7
Substituting this into B)
B) y + 8 = 9(y/7)
Multiplying both sides by 7
B) 7y + 56 = 9y
2 y = 56
y = 28
x = 4
***************************************************
Double Check
4 * 7 = 28 + 7 = 35
9*x = 36
Answer:
x = -18, y = 14
Step-by-step explanation:
4x + 6y = 12
x + 2y = 10
Divide both sides of the first equation by 2. Write the second equation below it.
2x + 3y = 6
x + 2y = 10
Rewrite the first equation. Multiply both sides of the second equation by -2 and write below it. Then add the equations eliminating x.
2x + 3y = 6
(+) -2x - 4y = -20
-------------------------
-y = -14
y = 14
Substitute 14 for y in the second equation and solve for x.
x + 2y = 10
x + 2(14) = 10
x + 28 = 10
x = -18
Solution: x = -18, y = 14
Answer:
You can multiple it separately
Step-by-step explanation:
1). 347 multiplied by 24 can be done like 347 by 20 and 347 by 4. Then you add them up and get your answer
