Answer:
Step-by-step explanation:
Let Freda's sum = x
Donnie has 3/4 x
He spends 63 dollars. His sum is now
3/4x - 63
Now the equation looks like this
6(3/4x - 63) = x Remove the brackets
6*3/4 x - 378 =x
6 * 3/4 = 4 1/2
4 1/2 x - 378 = x Add 378 to both sides
4 1/2 x = x + 378 Subtract x from both sides
3.5 x = 378 Divide by 3.5
x = 378 /3.5
x = 108
Since x = 108, that's how much Freda had. (She spent nothing).
44 - 15 i is the correct answer
Answer:
x = 7
Step-by-step explanation:
Let's solve your equation step-by-step.
10x−27=2x+29
Step 1: Subtract 2x from both sides.
10x−27−2x=2x+29−2x
8x−27=29
Step 2: Add 27 to both sides.
8x−27+27=29+27
8x=56
Step 3: Divide both sides by 8.
8x/8=56/8
x=7
