Answer:
2(2x + 4) – 3(x - 1) = 11
4x+8-3x+3=11
4x-3x+8+3=11
x+11=11
x=0
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
Given
2(2x + 4) - 3(x - 1) = 11 ← distribute parenthesis and simplify left side
4x + 8 - 3x + 3 = 11
x + 11 = 11 ( subtract 11 from both sides )
x = 0
Answer:
it's going to be no solutions. it cancels itself out
Step-by-step explanation:
6x+6-3x=6+3x
3x+6=6+3x
To find out how many posters you can buy for $48 given that three posters cost $9.60, you can set up a proportion and solve for x.
To find out how many posters you can buy for $48 given that three posters cost $9.60, you can set up a proportion.
First, find the price per poster: $9.60 ÷ 3 = $3.20 per poster.
Next, set up the proportion: $3.20 is to 1 poster as $48 is to x posters.
Cross multiply: $3.20x = $48.
Divide both sides by $3.20 to solve for x: x = 15.
Therefore, you can buy 15 posters for $48 at that rate.
