Answer:

$x = 16$

Step-by-step explanation:

Step 1: Add 79 to both sides

$10x - 79 + 79 = 2x + 49 + 79$

$10x = 2x + 128$

Step 2: Subtract 2x from both sides

$10x - 2x = 2x - 2x + 128$

$8x = 128$

Step 3: Divide 8 from both sides

$\frac{8x}{8} = \frac{128}{8}$

$x = 16$

Answer: $x = 16$

Mike went to a football game with his family. They bought 5 boxes of popcorn and 3 programs, and spent $41. Sean's family went t

EZ!

Let's say each box costs $X and each program costs $Y
Thus, Mike's family spent:
$(5X+3Y)
or
$41

Sean's family spent
$(3X+2Y)
or
$26

This yields us a system of two equations:
5x+3y=41
3x+2y=26

5x+3y=41
2y=26-3x

5x+3y=41
y=13-1.5x

5x+3(13-1.5x)=41
y=13-1.5x

5x+39-4.5x=41
y=13-1.5x

0.5x+39=41
y=13-1.5x

0.5x=2
y=13-1.5x

x=4
y=13-1.5x

x=4
y=7

Each box costs $4 and each program costs $7
