Answer:
x = -2
Step-by-step explanation:
To solve, we need to <u>isolate "x"</u> by moving other numbers to the right side of the equal sign. To "move" a number, <u>do the reverse operation to both sides of the equation</u>. <u>Move numbers in reverse BEDMAS order</u>.
4(-2x - 1) = 12 Do the opposite of times 4
Divide both sides by 4
-2x - 1 = 3 Do the opposite of subtract 1
Add 1 to both sides
-2x = 4 Do the opposite of times -2
Divide both sides by -2
x = -2 Solved for "x"
Answer:
17.50
Step-by-step explanation:
you really don't need to know the tax amount.
20% of x = 3.50
(20/100) x = 3.50 Divide top and bottom of the left number by 20
(20÷20) / (100÷20) * x = 3.50
(1/5) x = 3.50 Multiply both sides by 5
x = 3.50 * 5
x = 17.50
The meal cost 17.50
