3 shirts + 2 pants. adding the cost of the shirts and the cost of the pants. so 3 * how much the shirts cost + 2 * how much the pants cost give you your total.
Answer:
y=5 x=3
Step-by-step explanation:
x-y=-2 move the y over to isolate x
x=-2+y Now plug that in for x in the first equation
2(-2+y)-y=1 Distribute
-4+y=1 Add 4 on both sides
y=5
x-5=-2
x=3
Answer: Hope this helped(tried my best thinking what the question was asking)
x=0
y=-3
Step-by-step explanation:
(Im going to add and subtract)
Add:
14x-12y=36
14x+9y=-27
28x-3y=9
Subtract:
-14x+12y=-36
14x+9y=-27
21y=-63
y=-3 (substitute in first equation)
7x+18=18
7x=0
x=0
SO
y=-3 and x=0
Answer: (-2+√5), (-2-√5)
Step-by-step explanation:
<u>1.</u> Reference the formula: [(-b±(√b^2-4ac))/2a]
<u>2.</u> Plug in the values from the equation: [(-4±(√16+4))/2]
<u>3.</u> Simplify: [(-4±(√20))/2]
<u>4.</u> Simplify the root: [(-4±(2√5))/2]
<u>5.</u> Simplify the fraction: [-2±√5]
<u>6.</u> There's your answer: (-2+√5), (-2-√5)
Answer:
-3
Step-by-step explanation:
5x + 15 = 1x + 3
Add -1x and -15 on both sides.
5x - 1x = 3 - 15
4x = -12
Divide 4 into both sides.
4x/4 = -12/4
x = -3
The solution for the equation is x = -3.
