Answer:
6(2) -2(-5) Substitute the values given into the expression and multiply. 12+10 ... 1. 2x-(3-4y), when x = 5 and y=-3. 215)-(3-4(-3)). 10-(3+12). 10-15. 2. ... + (3 - 3 x + 1 +. 6-3x = 4x + 4. Bebetto. 2=7x -. - 4-2=34+12. - ý 2=2y+12. + ... y = 2x-1. Simplify. Subtract 2x from each side. Multiply both sides by -1. 2+3 m.
Step-by-step explanation:
If 2x + y = 7 and x + 2y = 5, then (x + y)/3 = (A) 1 (B) 4/3 (C) 17/5 (D) ... Divide both sides by 3 to get: x + y = 4 ... 2*(x+2y = 5) equals 2x+4y=10 ... or subtracting one from the other and it likely happens 90% times that ... If a question involves a system of two equations, and we're asked to find the value of ONE
Arjun should have divided both sides of the equation by 7 instead of multiplying.

Answer:
x = 2
Step-by-step explanation:
As you have indicated, you want to multiply both sides of the equation by 6x.

<em>Additional comment</em>
The denominator on the left is x. The least common denominator on the right is 6. To clear fractions, you can multiply by the product of these values: 6x. Doing this gave us the one-step linear equation 6 = 3x.
As with any operation performed on an equation, the operation must be performed <em>on both sides of the equation</em>. Here, we <em>multiply both sides by 6x</em>. It is a bit unconventional and confusing to show that multiplication as you have shown it in your figure. Usually, it would be shown as in the 2nd line of the solution, above.
Answer:
1. 15
2. -2
Step-by-step explanation:
First, since -4 is in parentheses, we want to take it out of parentheses. This might make sense but now it becomes 12 + 7 - 4. If it doesn't make sense, I'm sorry because I don't know how to explain it. Now we add 12 to 7 and we come out with 19. Then we subtract 4 and get 15. We want to do the same for number 2. We take -6.25 out of the parentheses and we have -1.75 - 6.25 + 6. When you subtract a negative something from a negative, we get more negative. So now we have -8 + 6. Which then equals -2. I hope this helps!
