Answer:
Let's solve for x.
4x+5y=7
Step 1: Add -5y to both sides.
4x+5y+−5y=7+−5y
4x=−5y+7
Step 2: Divide both sides by 4.
4x/4=−5y+7/4
x=−5/4 y+ 7/4
Answer: for the first one x=−5/4 y+ 7/4
3x−2y=−12
Step 1: Add 2y to both sides.
3x−2y+2y=−12+2y
3x=2y−12
Step 2: Divide both sides by 3.
3x/3=2y−12/3
x=2/3y−4
Answer:
x=2/3y−4
Step-by-step explanation:
512=2w^2 is the best answer

Step-by-step explanation:
Answer:
5/7
Step-by-step explanation:
Simplify by finding common factors and dividing both the numerator and denominator by it.
40/ 56 = 20/28(divided by 2) = 10 / 14 (divided by 2) = 5/7 ( divided by 2)
Hope this helps.
