1 + x = 7 − 2x solve the equation
ser-zykov [4K]

Answer:

x = 2

Step-by-step explanation:

Given

1 + x = 7 - 2x ( add 2x to both sides )

1 + 3x = 7 ( subtract 1 from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

The marching band sold gift wrap priced at $4.00 per roll for solid colors and $6.00 per roll for print patterns. If they sold 4
Alex Ar [27]

Answer:

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210

Step-by-step explanation:

Let

x ---> the number of gift wrap rolls for solid colors sold

y ---> the number of gift wrap rolls for sprint patterns sold

we know that

x+y=480 ---->x=480-y ----> equation A

4x+6y=2,340 ----> equation B

Solve the system by substitution

substitute equation A in equation B

4(480-y)+6y=2,340

solve for y

1,920-4y+6y=2,340

-4y+6y=2,340-1,920

2y=420

y=210

<em>Find the value of x</em>

x=480-y ----> x=480-210=270

therefore

The number of gift wrap rolls for solid colors sold was 270 and the number of gift wrap rolls for sprint patterns sold was 210
