4x-1=4x+7 regroup/ divide by the number next to x

Step-by-step explanation:

Given the expression 4x-1 = 4x+7, we are to simplify the expression and find the value of x. To do that the following steps must be carried out.

Step 1: collect the like terms by regrouping the expression

4x-1 = 4x+7

4x - 4x = 7+1

0x = 8

Step 2: Dividing both sides by the number next to x

0x/0 = 8/0

x = ∞

Any constant dividing zero will always return infinity as a value.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
