Answer:
Step-by-step explanation:
Study the steps used to solve the equation.
Given: StartFraction c Over 2 EndFraction minus 5 equals 7
Step 1: StartFraction c Over 2 EndFraction minus 5 plus 5 equals 7 plus 5
Step 2: StartFraction c Over 2 EndFraction plus 0 equals 12
Step 3: StartFraction c Over 2 EndFraction equals 12
Step 4: 2 (StartFraction c Over 2 EndFraction) equals 12 (2)
Step 5: c equals 24
-5-(15y-1) = 2(7y-16) - y // question
-5-15y+1 = 14y-32-y // distribute
-15y - 4 = 13y - 32 // subtract
-28y = -28 // divide
y = 1
Answer:
A) 29/8
Step-by-step explanation:
On the left side of the equals sign, we have five x's and nine -1's.
On the right side of the equals sign, we have three -x's and twenty 1's.
Both sides are equal, so:
5(x) + 9(-1) = 3(-x) + 20(1)
5x − 9 = -3x + 20
Add 3x to both sides.
8x − 9 = 20
Add 9 to both sides.
8x = 29
Divide both sides by 8.
x = 29/8
