The answer to 195x5 is 975
Answer:
<h2>y = 3x - 4</h2><h2 />
Step-by-step explanation:
3x - y = 4 ⇔ 3x - y - 4 = 0 ⇔ 3x - 4 = y ⇔ y = 3x - 4
2(-3y-1)+(2y+7)
Final result :
5 - 4y
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
-3y - 1 = -1 • (3y + 1)
Equation at the end of step 2 :
-2 • (3y + 1) + (2y + 7)
Step 3 :
Final result :
5 - 4
Answer:
14x + 6y = 10
14x + 35y = -77
Step-by-step explanation:
Multiply the top one by 2
14x + 6y = 10
Multiply the bottom one by 7
14x + 35y = -77
His next step is to subtract. You could have done this by multiplying the top one by -2
-14x - 6y = - 10
14x + 35y = -77 Now all you need do is add. The question now becomes what do you do? What answer do you give? I think the expected answer is the top two equations, but if I was actually doing the problem, I'd use the bottom 2.
